Two babies are in a pram together.
“Are you a little girl or a little boy?” the boy asked.
“I don’t know” the other baby replied.
“Let me check” the boy giggled.
So the boy went under the covers and came back up after several minutes.
“Your a girl!” the baby proclaimed
“Your so clever, how did you figure it out?”
“Its quite easy”, the boy explained, “You have pink socks!”
