1. ## A Lovely Little Riddle

Trying to think like a homeroom student...
2. ## A Lovely Little Riddle

I was thinking the same as Thalia. Let's see if this works. @plainglazed @Wilson @DudleyDude @fabpig Master Shakee hath returned.
3. ## Poisonous apples

I agree with Flamebirde's answer. But I would add a bit more to it.
4. ## The Executioner's Riddle

I'll count being in any way confused for Shakee as high praise. As for this one
5. ## Hot Love Riddle

Pretty sure it's one of these
6. ## Hot Love Riddle

Cats tend to be sort of lazy by nature, so that's my excuse. But to kick things off

8. ## Walk the pattern

Yes, and this has got to be among the most counter-intuitive properties of infinity that I know of.
9. ## Walk the pattern

Good, but now for the kicker. There's a reason I didn't specify the order in which I pulled out the rugs in the OP. After I finished pulling out every rug and walking the pattern forever, I went back and picked up all my rugs. Then instead of alternating odd-gons and 4x-gons, I placed two 4x-gons in a row before placing the next odd-gon. I still turned the same direction on every rug that I did before: still clockwise on every odd-gon and counterclockwise on every 4x-gon, so in the pattern 4-gon, 8-gon, 3-gon, 12-gon, 16-gon, 5-gon, 20-gon, 24-gon, 7-gon, 28-gon, 32-gon with clockwise tur
10. ## Walk the pattern

Clarification: when I walked the odd numbered N-gons I always turned clockwise. When I walked the multiple of 4-gons I always turned counterclockwise. For now, suppose I always alternated between an odd-gon and a 4x-gon without bothering to keep edge number monotonically increasing. So 3-gon, 4-gon, 5-gon, 8-gon, 7-gon, 12-gon, 9-gon, etc with clockwise turns on blue and counterclockwise on red. (Otherwise, yeah, it would be a mess.)
11. ## Walk the pattern

I once stood on a Cartesian plane at (0, 0) facing north (along the positive y-axis). I pulled out a rug in the shape of a regular triangle (which I call a 3-gon) and set it on the plane with one vertex at my feet at (0, 0) and with the center in the direction I was facing along the y-axis. I then started walking forward on the rug until I got to the center of the 3-gon, at which point I stopped and turned clockwise until I was facing a vertex, and I walked to that vertex of the 3-gon. Then I pulled out a rug in the shape of a square (which I call a 4-gon), put it with one vertex at my feet an
12. ## Coin hunt

That looks like it nailed it, PG! As for a way of saying it in under a minute...
13. ## I’m not Moby Dick

I'll call that a hit. My thinking was...
14. ## I’m not Moby Dick

Getting warmer, but I'll definitely cause you (the listener of the riddle) more calamity if my insides get out and have my own "peaked wave" in the sea to sit under (mostly).
15. ## I’m not Moby Dick

Not a balloon, something else that's more characteristically under a peaked wave and mostly concealed.
16. ## I’m not Moby Dick

On the right track, but I get more riled up upon harpooning.
17. ## I’m not Moby Dick

Not a sink disposal. While I imagine the last stanza has happened with some of those, I hope it's not commonplace enough to belong in a riddle.
18. ## I’m not Moby Dick

On the right track, but not quite there yet.
19. ## I’m not Moby Dick

I feast on meals of mindless fare With blubber to keep it all in For what’s inside should stay right there Or you’ll face a calamitous end ‘Neath peaking wave I spend the days While mostly conceal’d, I presume Unless my presence breath betrays As characteristic’s my spume Alas, I find myself engaged By man with a wretched harpoon Assaulted thus, I shriek enraged With hellish retort for the goon
20. ## Poisoned Needles

How I'm interpreting it so far:

22. ## Shortest set of lines in a square, revisited

Optimizing Captain Ed’s answer a little more
23. ## The Most Wonderful Prince

Is there an easier way to reach the solution? If I try to handle the case of an infinite number of princes to choose from, and I deal with the exact formula I was working with initially instead of the simplified approximation that I ended up using to be able to actually calculate an answer, then I get

25. ## Coin hunt

I know of a way to do this while flipping no more than two coins. And a hint:
