Can You Solve This Equation? A Collection of Math Jokes and Sayings

[MC363A]

If anyone out there can help me with coming up with some great math-related jokes or sayings, it would be very appriciated. There is a rather large project coming up, and I haven't started yet, but I will also post the ones I find if you are willing to help. I have heard a lot of great ones, but now I am kicking myself for not writing them down.
Thank you!

A google search brought me here. I didn't read them all (yet), but some of the ones I read were pretty funny (even the ones I've heard before). Is any of this along the lines you're looking for? BTW, I think your signature is hilarious.

This one is my favorite.

A limerick.
$$((12+144+20+(3*4^{1/2})))/7)+(5*11)=9^2+0$$
Do you know what it says to make it a limerick?

Two guys go into a bar, and well, they say curse words in math using a calculator. Isn't that funny as hell?
