Practical Jokes that Backfire

[Watertender]

Did you ever play or see a practical joke that backfired?
Where I used to work there was a guy who used to deliver packages throughout the maintenance building. He had a cart with a squeaky wheel so you could always hear him in the hallway.
One of the welders decided to play a joke on the guy and made a superhero costume. He had purple sweatpants with green shorts over them and a red sweatshirt with a black cape. On the cape and sweatshirt he put a big capital F in duct tape and declared himself as Fartman.
He heard the cart coming down the hallway and jumped out with his back to the cart and bent over with the cape pulled up like a set of wings. He rips this huge echoing fart and hollers... It's FARTMAN!!!
He turns around to see the boss and the secretary using the package cart to move some file boxes... The secretary says "You're an idiot" and keeps on wheeling the cart down the hallway. The boss says "Carry on" and walked away just shaking his head.

I was laughing so hard that I couldn't stop.

We had a SFC in our hangar that loved to sneak up on someone in a Huey hell hole and spray paint their boots with yellow paint. He picked the wrong guy one day. It was the leader of the sheet metal crew, in the hole, checking on how to repair a problem. When he came out he grabbed a 4" paint brush and some traffic yellow, walked into the break room, where the 'jokester' was having coffee, and painted his entire bald head yellow. The SFC got the message.

I busted a gut laughing at that one FM! I can just see a SFC after that happening!

Worked at a hospital for many years. We had a "floor guy" who vacuumed and mopped/swept floors throughout the hospital. A really nice guy. Well he was coming down a hall, and his supervisor and another worker decided to hide and jump out when he came by. It just so happened that he was walking with the evening charge nurse (basically the boss of the hospital during off hours). When they jumped out, they startled her more than him. He immediately grabbed his chest, and told the charge nurse, "I have a heart condition. See what these guys do to me?" (He actually didn't). Well the charge nurse ended up having a very long conversation with the other two......

My father came into work one day and there was a radio on his bench. So he plugged it in and put country music on.

His co worker Joe showed up and switched it to rock. My father turned it back to country.

Joe says of you don’t stop changing the station I will cut the cord off that radio. My father says go ahead. You don’t have the nerve to do it. Back and forth.

Finally Joe cuts the cord off. A few minutes later the owner of the company walks in and says. Sorry I left my radio on your bench this morning. My father says. No problem, but Joe cut the cord off. I think he has anger issues.

Joe ended up in mandated anger management!
