7-UP

I was sitting in the waiting room of the hospital after my wife had gone into
labor and the nurse walked out and said to the man sitting next to me,
"Congratulations sir, you're the new father of twins!"
The man replied, "How about that, I work for the Double mint Chewing Gum
Company." The man then followed the woman to his wife's room.
About an hour later, the same nurse entered the waiting room and announced
that Mr. Smith's wife has just had triplets.
Mr. Smith stood up and said, "Well, how do ya like that, I work for the 3M
Company."
The gentleman that was sitting next to me then 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."
The man continued, "I work for 7-UP."
