This little boy was at school one day and had to use the bathroom really bad. So he raised his hand and told the teacher he had to use the bathroom really bad.

She said, "ok well let me hear your ABC'S first."

"A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,,Q,R,S,T,U,V,W,X,Y and Z" replied the boy.

The teacher said, "that's great but where's the P?"

The boy replied "it's running down my leg!"
