Little Johnny asked, "Mommy what's that between your legs?
She told him that was her squirrel. Later that day he was in the bathroom again while grandma was taking a shower and he asked, "Grandma what's that between your legs?"
She replied, "That's my squirrel."
Little Johnny said, "Mommy has one too, but hers is not as grey as yours."
Grandma replied, "Well, your mommy's squirrel hasn't cracked as many nuts as mine has!"
