So, today in art....Me:  Why are you yelling?  Student 1:  I AM NOT YELLING, I JUST TALK LOUD!  Me:  OMG!!  If you were one of the X-Men you would be the Banshee, the guy whose mutant power is to yell all the time.  Student 2:  Who would I be Mr. Smith?  Me:  You would be Gravity, cause you are always falling down, proving the theory of gravity is true.
