For Amplet...
In that fine city of Minneapolis one evening there are three nervous expectant fathers in the waiting room of the hospital. (Back in the day when the fathers were in the waiting room and not bedside hearing their beloved whisper sweet nothings to them.)...
The nurse comes out... Mr. Johnson congratulations your wife gave birth to healthy TWINS! "Wow, what a coincidence, I'm a groundskeeper for the Minnesota Twins." (Thus this joke in this thread)
A bit later...
"Mr. Smith, your wife just had TRIPLETS!" "That's strange, I'm a manager for 3M."
At which point contestant number three heads for the door.
"Don't leave Mr. Anderson, your wife is due any moment."
"I'm gettin' the hell outa here... I work at the 7-UP bottling plant."
