    In our circles you may find A laugh, a wink, a grin But pressure us we'll likely snap And send away our kin. We don't do much, we go to pot Such simple ones are we But with your hand we take command Or from you we will flee.

    Agree. When I hit the send button, I realized my thinking was too simple. But instead of deleting my post (moderator privilege) I left it to take its licks.

    (This puzzle is from a blog called By Way Of Contradiction.) Imagine you have a circular cake, that is frosted on the top. You cut a d degree slice out of it, and then put it back, but rotated so that it is upside down. Now, d degrees of the cake have frosting on the bottom, while 360 minus d degrees have frosting on the top. Rotate the cake d degrees, take the next slice, and put it upside down. Now, assuming the d is less than 180, 2d degrees of the cake will have frosting on the bottom. If d is 60 degrees, then after you repeat this procedure, flipping a single slice and rotating 6 times, all the frosting will be on the bottom. If you repeat the procedure 12 times, all of the frosting will be back on the top of the cake. For what values of d does the cake eventually get back to having all the frosting on the top?

    I swear: 1) To strangle the next person who uses 'suicide' as a verb. 2) That if I offended or hurt you in any way, I didn't mean it. 3) That I'll stop procrastinating. Tomorrow. Add whatever you swear.

    Personally, the original reason I believed in God is that an adult told me he existed when I was little and, being little, I took their word. But over time, I've listened to people talk about their experiences with God and seen it with others. I think I've seen Him get me through a lot of stuff the past few years that I don't think I'd have been able to make it through alone. You could say that I got through them because I worked hard, or just because believing in a higher power has some effect psychologically, or that there were coincidences involved, but when I put it all together, those reasons just don't work for me. But if I had to give just one reason that I believe God is real, it would be that He told me so. Audibly.

    this one is pretty cute! Blonde v.s. Lawyer a lawyer sitting on a plane next to a Blonde want to pass some time and turns to her and says, "how about a trivia game, if i ask you a question and you get it right I'll pay you 10 dollars, and if you get it wrong you pay me 1 dollar. then you ask me a question, with the same conditions." blonde says, "no thanks, I'm reading a book." the lawyer says, "okay how about this, 20 dollars for getting right for you, and 20 dollars for getting wrong for me." the blonde rolls her eyes and says fine. the lawyer asks, "whats the distance from the earth to the sun?" the blonde hands him a dollar. then the blonde asks him, "what goes uphill with 3 legs and down hill with 4?" the lawyer blinks for a second and says " i have no idea, i guess you win that round." then hands her 20. "okay my turn again, i am curious, what does go up hill with three legs and down hill with 4?" the blonde hands him another dollar.

    I would think that the only way to make ANY sense of the situation is for the woman to repeat back to the croc EXACTLY what he said to HER: "If I guess right, you'll give my baby back, if I dont, you'll eat him. That's what you'll do to him." He'd have to return the baby, because she's CORRECT NO MATTER WHAT. Eh? hehehe

    We are in a TV game. We have 8 same looking boxes, each of which has 2 pebbles. Each pebble could be either precious or not precious. We choose a box and the host, without looking inside the box, pulls out a pebble. It comes out to be precious. The TV host then declares that we have exactly 50% chance that the 2nd pebble inside the box is precious, too. If we know that, in the beginning of the game, the count of precious pebbles is no less than the count of not precious pebbles, which of the statements MUST be true? We assume that the TV host knows the pebbles distribution in the boxes - in what amount of boxes the precious pebbles are 0,1 or 2. The TV host, however, doesn't know the kind of pebbles in each specific box, as he himself doesn't differ the boxes from one another. 1. If we swapped the boxes, we would have higher chance of picking up precious pebble next. 2. If we swapped the boxes, we would have same chance of picking up precious pebble next. 3. If we swapped the boxes, we would have lower chance of picking up precious pebble next. 4. In the beggining of the game, there've been exactly 2 boxes with 2 precious pebbles each. 5. In the beginning of the game, half the boxes have had 1 precious and 1 not precious pebble. 6. In the beginning of the game, the precious and not precious pebbles have been equal in count. 7. In the beginning of the game, the amount of boxes with 2 precious pebbles is equal to the amount of boxes with 2 not precious pebbles. 8. The TV host has gone wrong. There's no way that there's 50% chance for 2nd precious pebble in our box, as there is unequal amount of pebbles left in the game. 9. None of the above must be true.

    Though seldom seen, I'm world renowned Ever in flight above the ground. Teeth chewing, gnashing in time gnawing on knots, shunning the find. My hands at the ready, arms at the stay Heart like the sun, burning away. Ears like a rabbit's, pinned to the side-- Listening close, far and wide.

    We're being intruded by migrants secluded Who stowaway past our frontier They're costing us green and will linger unseen Unless I should get into gear Their nature I'll dredge as I perch on a ledge And twisting the truth's my endeavor Exposed to the nation, and next: deportation They thought they'd endure thus forever? I promise the answer has nothing to do with politics

    In an insane asylum, three patients are up for release. The Doctor decides to give them an intelligence test. He turns to the first man and asks, "What is three times three?" "274," he replies. The Doctor asks the second man, "What is three times three?" "Tuesday," replies the second man. The Doctor turns to the third man, "Okay, your turn. What's three times three?" "Nine," says the third man proudly. "That's great!" says the doctor. "How did you arrive at that?" "Simple," says the third man. "I subtracted 274 from Tuesday."

    Three interstellar stations have observed a distant cluster of gas clouds known as RGB-9. The stations are positioned at right angle with each other. The photograph images captured by X,Y, & Z telescopes at the same instant are having exactly the same configurations (see below). Some of the gas clouds that are behind the other cloud emits a mixed spectrum.. How shall they construct the 3-D plot of the cluster?

    Until this posting, it was a fairly well-kept secret that I am a card-carrying member of the DENSA society. That is not a typo. DENSA is an acronym for Diversely Educated, Not Seriously Affected. DENSA membership requires supplying the correct answer to the following multiple-choice question. 1. How many stars are there? a. All of the above.

    An engineer, a physicist and a mathematician are staying in a hotel. The engineer wakes up and smells smoke. He goes out into the hallway and sees a fire, so he fills a trash can from his room with water and douses the fire. He goes back to bed. Later, the physicist wakes up and smells smoke. He opens his door and sees a fire in the hallway. He walks down the hall to a fire hose and after calculating the flame velocity, distance, water pressure, trajectory, etc. extinguishes the fire with the minimum amount of water and energy needed. Later, the mathematician wakes up and smells smoke. He goes to the hall, sees the fire and then the fire hose. He thinks for a moment and then exclaims, "Ah, a solution exists!" and then goes back to bed.

    Alright, let me take a crack at it guys..... The confusing part about this riddle is the word Pear. As you can see above there has been some talk about its ability to be placed FAIRLY in text. Reason being, it is more a PLAY ON WORDS then it is a riddle. Example = You have a "pear" that you eat. FRUIT... Example2= You have a "Pair" of socks. PLURAL... The question states that there are PEARS on the tree, but once the wind came there were no longer PEARS on the tree OR on the ground... HOW COME??? Problem with the question is, if you typed it properly, THERE WOULD BE NO QUESTION. So you HAVE to trick the reader in order for it to HAVE THE PROPER EFFECT. Problem with that is "If this is a Problem Solving Forum, you need to give an Accurate Problem" This riddle is IMPOSSIBLE to TYPE, It must be Spoken in order to work. Other wise the question would be as follows: There are a Pair of Pears on a Pear tree...lol After a wind blew, there were No Longer a Pair of Pears on the tree... WHY? Of coarse the answer would be: BECAUSE ONLY ONE FELL OFF, LEAVING ONE PEAR ONE THE TREE, AND ONE PAIR ON THE GROUND, ELIMINATING ANY PAIRS OF ANYTHING, ANYWHERE..... If that doesn't do it, I don't know what to tell ya.... -= Veracity =-
