Two little babies were sitting in their cribs, when one baby shouted to the other, "Are you a little girl or a little boy?"
"I don't know," replied the other baby giggling.
"What do you mean, you don't know?" said the first baby.
"I mean I don't know how to tell the difference," was the reply.
"Well, I do," said the first baby chuckling, "I'll climb into your crib and find out."
