I was sitting in the waiting room of the hospital, after my wife had gone into labour, and the nurse walked out and said to the man sitting next to me. "Congratulations sir, you are the father of twins".
The man replied "How about that, I work for the Doublemint chewing gum company".
An hour later the nurse came in and announced that Mr.Smith's wife had had triplets. Mr Smith stood up and said "Well how do you like that, I work for the 3M company".
Then the man sitting next to me got up and started to leave, When I asked him why he was leaving, he remarked. "I think I need a breath of fresh air, I work for 7-up.
