I refereed once.
When I was a student at Iowa back in the 60s the intramural office was looking for referees and it sounded like a good way to make a buck. My first game was a goddam nightmare. It was like a zoo with all the animals out of the cages and desperate for meat. Figured most of the players couldn't make their high school teams and wanted to show their stuff. Complete thugs. We were playing 6 minute quarters with no clock stop for anything. Early in the 2nd quarter the main little prick slugged a guy on the other team. I blew the whistle, grabbed the ball and yelled "Forfeit!" and headed for the office. They went crazy. I hid in Dr. Beebe's office for about 2 hours cause I was afraid to go outside. Apparently they got tired of waiting for me.
