The person who came up with the solution for this is WRONG!!!

The lion lies every Monday, Tuesday and Wednesday and the other days he speaks the truth.
Lion said: Yesterday I was lying and two days after tomorrow I will be lying again.

People are expecting the lion to be telling the truth in this statement, when in fact, the only way to make the statement true, is to assuse that what the Lion is NOT speaking the truth. (Take everything the Lion says to mean the opposite.)

The answer is Monday
He was actually speaking the truth yesterday (Sunday) as well two days after tomorrow(two days after Tomorrow [tomorrow being Tuesday] is Thursday), therefore.... Today is Monday, a day that the Lion lies!

I would say Monday too, we need a specific day for the answer.

However, Why does the puzzle include a Unicorn as he plays no part.

I think I more interesting question would be:
Which day did the lion say this, and did the Unicorn agree with the lions statement?

i'm surprised that no one considered the semantic argument... when we are informed that the lion lies on monday, tuesday, and wednesday, we cannot be certain this fact describes a propensity toward fibbing, as all here have assumed, or merely a state of recumbency. homonyms, anyone?

The correct answer can only be Monday, especially when considering the laws of logic (I took a class on this, so hopefully I would know. The concept that the statement is only considered true when all parts of it are true (A ^ B.) is only accurate on a day when the lion is only telling the truth. This is because we assume that on a day when the lion is telling truth, A means A. However, on a day when the lion is only telling a lie (or the opposite of the truth), then we must assume that A actually means ~A (not A). So whereas on a truth day we are looking for both A and B to be true (A ^ B.), on a lying day we are in reality looking for everything to be NOT the truth, therefore we are actually looking for (~A ^ ~B.) to be true. This is only fulfilled on a Monday. (A ^ B.) is never fulfilled, so the only possible day is Monday.

I agree with rookie1ja, I think a statement is false as long as one part of the statement is false, however if it was said in two different sentences then the only answer could be monday.

I am agreeing with the answer being Monday. I may not have a big long drawn out answer from logic classes with A's and B's and stuff. But the lion has to say this statement on a day he lies. "Yesterday, i lied and two days after tomorrow I will lie again." Yesterday (being Sunday, which he speaks the truth) so lying fits (because it's Monday) and then two days after tomorrow (which is Thursday, a day he tells the truth) "I will lie again" is also a lie.


And I think they throw in a unicorn and days he lies and tells the truth to throw the people off because they will look to deeply into trying to get the answer. The question was only about what day the lion said the statement, which clearly has nothing to do with the Unicorn.

It looks like Monday is the correct solution but it isn't.
I have to agree with rookie1ja.
The lion said the phrase in one sentence. It mean that he can say that sentence on a Tuesday.
Example:
Consider me a liar.

I didn't eat the pig yesterday infact i'm eating it right now.

In reality I'm not eating a pig right now so it means that the sentence is false.
Does this means that I eat a pig yesterday ????!!!!

My head says any lying day; my heart says Monday.

What does the unicorn have to do with this?

the answer HAS to be monday because if it was tuesday and he said "i was lying yesterday" then he would be telling the truth (because monday is a lying day) and he does not tell the truth on tuesdays.
