There was a little baby boy and a little baby girl side by side in the nursery at the maternity ward. The little baby boy says to the little baby girl, "I'm a boy, you are a girl!"

So about 10 minutes later, the nurse leaves. When she was gone, the little baby boy lifts up his gown and says.........

"See I have Blue Booties, and you have Pink!
