I knew a guy, high school student in the late '60s. He and his best friend were very close, but had also dated the same girl. My buddy dated this girl first, now the friend was dating her. No problems, but they both understood how this could be perceived as a potential friendship ender.

They had a joke all planned out. The best friend grabbed some ketchup packets from a fast-food restaurant. After lunch, he was sitting in class with the packets torn slightly, tucked unnoticeably in his hand. My buddy had the starter pistol from the track and field team. You see where this is going.

My buddy ran into the classroom and shouted, "YOU CAN'T STEAL MY GIRL FROM ME!!! IF I CAN'T HAVE HER, NO ONE CAN!!!" He fired the starter pistol (filled with blanks, not bullets) in the direction of his best friend. The friend, who had jumped up from his desk during the shouting, clutched his chest from the fake bullet wound, sending horrifying streaks of red (ketchup) flying all over his white t-shirt. He collapsed.

The look of horror on the face of every student in the room, my buddy said, was amazing. He and his best friend both got detention.

...

Sometimes I think about this story, and I wonder what would happen if high school students tried this in a post-Columbine world. It's crazy how much times change in just a couple of generations.

Kid in my band class still thought yo mama jokes were funny.

We came back to school for the first time after hurricane Sandy, and the kid goes to the teacher ,"yo mama s-" and the teacher cuts him off "died in the hurricane"

The kid never told another one of those jokes in that class.

He loaded up p**n on someone's computer while they were in the bathroom. Teacher wasn't paying attention and the victim ended up getting suspended.
