Three expectant fathers were in the waiting room.

The nurse came out of the delivery room and announced to one of the fathers that he was the father of twins.  He was delighted and said what a coincidence, since he was a member of the Minnesota Twins team.

A little later the nurse came out again and said to the next father, congratulations, your wife just had triplets.  He was so a happy - and said isn't that a coincidence - I work for 3M.

The other father took off like a shot - the nurse ran after him saying where are you going?  Over his shoulder, the nurse heard him mumbling something about his work at 7UP.
