I've seen them several times before but still find the infinity and suicide one pretty funny.

I've seen them posted up in a Tipps (tutor) classroom...lol

 

[Forbidden.]

My friend's maths teacher happened to photocopy them for the student's laughing pleasure ... the expand one is a classic, except i should have done it in the preliminaries for fun.

....*snicker*

I haven't seen the hangman one before but the rest are printed out on the maths noticeboard. xD

For the first one... But I think I've said that before.
