Two 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". He carefully got himself into the other baby's
crib, then quickly disappeared beneath the blankets.
After a couple of minutes, he resurfaced with a big grin on his
face. "You're a little girl, and I'm a little boy," he said
proudly.
"You're ever so clever," cooed the baby girl, "but how can you
tell?"
"It's quite easy really," replied the baby boy, "you've got pink
socks and I've got blue ones."
