Four Dads

Four men are in the hospital waiting room because their wives are having babies. A nurse goes up to the first guy and says, congratulations! You're the father of twins. Thats odd, answers the man. I work for the Minnesota twins! A nurse says to the second guy, Congratulations! You're the father of triplets! That's weird, answers the second man. I work for the 3M company. A nurse tells the third man, Congratulations! You're the father of quadruplets! That's strange, he answers, I work for the four seasons hotel! The last man is groaning and banging his head against the wall. What's wrong asks the other dads? I work for the 7 up company.
