For the record, I would not want to know I am a new dad via a recorded surprise from inside the fridge. My reaction would probably be pretty similar. Which may be why I think it is so funny.

So this guy is going to to the fridge for a cold one and his girlfriend or fiance covered his beer bottles. They all say "Daddy's Beer". He didn't get it at first, but once it sank in the reaction was priceless!
