Because it kept running out of the pen!! My favorite joke when young :).
They both run at the first sign of emotion.
Because all of the Mexicans that can run,jump,and swim are in America!
A favorite joke of my mother) The Q because is a big zero with a small tail.
She's got a tampon behind her ear and she can't find her pen.
It's mother was in the pen and it didn't know how long the sentence was.
