With a nod to Bill Engvall: So I'm at a delivery of a baby this morning. C-Section, no problems. We clean the kid up, check him out head to toe and we are preparing him for mom to hold. The dad is standing there while we are doing this. The last thing we do before we swaddle him and take him to see mom is we put a diaper on him. The dad looks at us and asks: "Is that his first diaper?" Here's your sign.
