Four men in the hospital

Four men are in the hospital waiting room because their wives are having babies. A nurse approaches the first guy and says, “Congratulations! You're the father of twins.” “That's odd,” answers the man. “I work for the Minnesota Twins!” A nurse then yells the second man, “Congratulations! You're the father of triplets!” “That's weird,” answers the second man. “I work for the 3M company!” A nurse goes up to the third man saying, “Congratulations! You're the father of quadruplets." “That's strange,” he answers. “I work for the Four Seasons hotel!” The last man begins groaning and banging his head against the wall. “What's wrong?” the others ask. “I work for 7 Up!”
