Liar, Liar, pants on fire! I tried to go through the thread to see if this one was listed and didn't see it...but this is a LOOOONG thread! I might have missed it.

A lot of the monkey rhymes were already mentioned but this is one that I recall:

Good morning to you,
Good morning to you,
You smell like a monkey,
and you look like one, too!

I think I can relate to that last one... :-)
