My wife is a Banquet Manager and does dozens of weddings a year. At one the groomsmen dragged their bus driver into the parking lot and beat the hell out of him. One of them claimed he looked at one of the bridesmaids “funny”.
So much for their ride home.
I know a guy who started a fistfight at his own wedding. I never found out what it was about. And yes, the guy loves his booze...which might have had something to do with the fight. (snicker)
