Pranked the grandson today

[Triplegreen500]

Big HVAC zip ties on driveshafts or cv axles.

Gravel in hubcaps.

Pull the hubcaps. Pull the wheel lugnuts off. Replace the hubcaps. Soon as they turn the wheel to get out of the parking spot, the wheels collapse and the car drops like 6". Not recommended for "nice" cars, but if your buddies drive beaters....or if you really don't like your school disciplinarian...

Building a VW squareback in the cafeteria one night.

Replace the sodas in the vending machines with cans of beer.

Wire the horn to the left turn signal...or the brake light switch.

Fill their hard hat with water and put it in the freezer overnight.

Back in the days when I was an apprentice..... we had steel caps boots with the steel on the outside.
Often in the morning your boots would be welded to the steel work bench.

Another one that worked a couple of times - the workshop phone was the old style with a cord and a handset.... bearing blue on the earpiece happened more than once. Too late once you realise it after hanging up.

Also..... charging up the capacitors in the storeroom was funny..... for a few of us. A 500-Volt hand-cranked Megger was the ticket. Apparently also useful for lake fishing....so I have been told.

I sprayed CRC-556 all over the element of a floor fan-heater once just before morning break. I left the heater switched on full heat, and high-speed fan.....turned the test switch off on the board. I also aimed the outlet at the desk so that when my 'Tradesman' came back to finish he got the full smoke job. It worked......he wasn't happy about it.....funny as hell with a massive white cloud of smoke in the workshop.

A military friend I worked with rode a Harley, I had a Honda V-65 Magna at the time. One day I put a puddle of oil under his bike, we both laughed. The next day when we left work, there was a little pile of rice under my bike! Good times!!

Actually you taught him the correct way to park. More of a lesson than a prank.

THIS sort of stuff is funny for 99% of us. We think back with fond memories of it and have a smile.
To heck with the 1 % that can't handle it!

I happen to be working at the college my grandson attends and when I spotted his car in the parking lot,it was on.
This is the things I missed out on as a kid. My grandad was not as cool as me.
I purchased the car for him so I have an extra key to his car in my truck.
Well it would only be right to mess with him a little. So I turned his car around. He said he noticed something was different but didn’t know what it was until he was in the car. He stepped out of the car and looked at the car and was puzzled because he knew he didn’t back in.
When he got home he told my wife/ grandma something weird happened at school and he’s not sure what was going on. She played along until she couldn’t take it anymore.
I texted the picture's to him and told him to check his messages.
He’s still laughing every time he looks at me. Good stuff and good memories. I think I qualify as a cool grandpa. We’re still laughing.

You should prank him with a new set of wheels
