Two little babies

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."

He carefully manoeuvred 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."
