As is Peter Falk.

On a baseball trip, our catcher fell asleep on the bus totally passed out from a double header. Mid summer and we had just stopped at the store to stock up for the ride home. We had fountain drinks so one of us put ice on the crotch of his pants to melt. I put pine tar on the straw of his drink. We tied his shoelaces to the seat post. And lastly we put rosin, chalk from the pitching rosin bag, in his hat.

He was not happy.

We once put a dead fish in some friends' oven on low heat while they were away on vacation.

On a camping trip with some friends, I took one of the spark plug leads off, left it just covering the plug. He drove all the way home (about 50 miles) on 3 cylinders, and around town for a week, even had it serviced and they didn't find it. (Not getting my car serviced by that team). Before someone pushed the lead back on.

This one isn't mine and it's rather demented.

Friend of mine, newer friend, let's call him TRH, I've only known him for 2+ years, used to live on the east coast in a wooded area. He lived by an elderly gentleman that use to yell had him every chance he got. TRH was approximately 6-7 years of age.

Anyway, TRH got to the point where he couldn't stand the old man yelling. If he was yelling for a reason, I don't know. So, for a full summer, THR would find all the smaller animals that had died in the woods, take them back to the old man's house and climb up on his roof via a wood pile and throw them down his chimney. Flue was closed the little gritters would stay in the chimney.

I don't know the outcome of this story as he got into a laughing fit.

Did anything bad happen to the motor?

Sounds like a great beginning to a Stephen King novel

Also sounds like a future client for maddragon13...

Ooh I wanna share. Back when cell phones had camera capabilities I had gotten one right off bat. I kept it till my contract was up then I went to another service. So I take the phone was still pretty good and threw it on ebay. The guy who bought it was nice at first. Then started emailing me about how I needed to ship it right away and send it overnight. This was one day after he won it. also I didn't offer overnight. But he started threatening me and calling me out of names. His excuse was it was a present to his best friend. So I take his phone and proceed to take pictures of a body part that leave a lot of questions. Send it out. Two weeks later I get an email said "Not cool man, now he thinks I'm gay.".
Mission accomplished.

I don't recall, but the guy was a bit of a mental case when it came to cars, another car he had, he rang up saying he had a leaky radiator, we drove out to support him if he needed picking up, followed him home for about 5 miles, the smoke from the car was alarming.

These tales remind me of
Marge Simpsons "Kids can be so Cruel"
Bart (overhearing the comment) "Wow, thanks Mom."

Camping in the wood and dressing in all black scaring random people at night..... and ......... Throwing cut up steak under tents so the racoons can scratch at them during the different hours of the night.

Had one played on a group of people on a camping trip, 30 of us on a bus trip, we overnighted at Ayers Rock (look it up) set up our tents, laid out our sleeping bags and went off the see the sight. (In the area a small hopping mouse lives (Jerbora) at the time in plague-like proportions.)
It was kind of payback as we had gone "tent-pegging" the little beggars around sunset.
A couple of helpful lads loaded each sleeping bag up with a chocolate sweet, most were found and disposed of outside the tent, but the smell was still there. The entertainment when some small rodent driven mad by the smell of chocolate is trying to get into your sleeping bag climbing across your face is most humourous (not).

Favorite prank of all time.

My freshman year English teacher was afraid of Smurfs. I had her class first thing in the morning. Our class got together and decided to put a Smurf mural all the way around the room on the 4 blackboards. When the teacher walked in to teach that morning we were all sitting at our desks and we started singing the Smurfs theme song. She was out for the next week and we later found out that she landed in a mental institution for a short time.

Clear tape from the street sign on one end of the road to the fence on the other side of the road. Windshield height. Never done it but know some who have.
