If you have a friend taking a flight sometime soon: Get some sheet metal and cut out some shapes of handguns, knives and such. After cutting the shapes place them on the inner part of you friends suitcase. When he arrives at the security point and they x-ray his bags he's in for a nice surprise. Place bologna slices all over your friends car during a nice warm/hot day. Make sure they'll be there for several hours. Something in the bologna soaks up auto paint. After your friend removes the slices he has a polka-dot mobile.
RocketMan Tex pulled the most alarmingly disgusting prank I have ever heard of. I'm sure he'll pop in to describe it. Lil Pun --- *LOL* the airport one is great. I'd love to see that happen (not to me of course).
Here are two of my better ones....now that I think about it, they were on the same guy. He and I were big Oilers fans, so I have no excuse for this first one. He always used to pass out during parties, and we were partying pretty hard one Saturday afternoon during college, and of course, he ended up in a fetal position on the couch. He used to shave his head in the summer and then let it grow back out. At this time, he had about two or three weeks of growth on his head. I had some good friends in town, and they were all from Dallas. Of course, they were cowboy's fans. I didn't just allow this to happen, I instigated it....and I even cut out the templates in cardboard (kinda stupid of me in retrospect....seeing as how I hate the cowboys). Basically, we used a razor to shave a stripe down the middle of his head from the middle of his forehead to the middle of his hairline at the top of his neck. We then used cardboard "star" templates to shave stars on either side of his head. Basically, we made his hair look like a cowboy's helmut. The next one was really mean. We lived in an old warehouse that had been converted to apartments, and all the people on the second floor were in our "group." We had a rule that if you passed out some place other than your own bed, you were fair game to be messed with. It was a Sunday afternoon after a keg party, and there was beer cups all over the place with old stale beer from the night before. I grabbed one that was half full and poured it into a blender. I then grabbed several dozen chile de arbol's (quite a bit hotter than jalepenos and dried {so they're concentrated}) and put them into the blender and whirred the whole thing into a paste. I then strained the whole thing into a glass, and I ended up with about a shot glass of this red liquid that smelled like beer. My buddy was passed out on someone's coach (again....in a fetal positon), and all he was wearing was his golf shorts. The front pocket was kind of sticking open on his side that was facing up, and I slowly poured the liquid into his pocket. I then went back over to my apartment, and the rest of us fired up a movie. About an hour or so later, he walked in with this look of fear on his face. He was hunched over with both hands holding his package. He looked at us and said, "did someone mess with my dick?" I think he spent the next few hours soaking in a tub. Good times.
How about this one, my friend did it to his girlfriend. My friend's girlfriend has a cat, and everyday he would clean out the cat's literbox before she got home. He would continue to clean out the literbox whenever he would see the cat had craped in there. The girlfriend started to get concerned because the cat was not using the literbox anymore. After about a week or so, she really got concerned about the cat. My friend just told her the cat was probably constipated and would be fine. After about another week, before the girlfriend was about to go the vet, my friend took an enormous dump in the literbox and pretended that the cat did it.
Here is one I did when I worked at Barnes & Noble. During a break one of my fellow employees fell asleep in the magazine section. A co-worker and I thought it would be a good idea to place an open Play-Girl face down on his lap. While he slept there people just walked by laughing at him. When he finally awoke and he saw what was on his lap, he jumped up and threw it off his lap in terror.
Interesting friend there. George Clooney said he did the same thing to his roommate on The Tonight Show a few years back.
i was at a foley's in a mall with a friend. he had finished purchasing a shirt that had one of those sensors on them. as he walked away from the cashier i quitely asked her for the sensor and stuck it in another bag that wasn't the foley's one. well, the alarm went off a couple of times and i was busting his balls about stealing. the girl checked his bag and found nothing (she knows what i did) and said he could go. after the second time, i told him what i did as he was clearly getting agitated and somewhat embarrassed b/c there were a couple of people looking. it was still funny though.
Place a loose toilet in the elevator of some office building, sit on it and start reading news paper, when people try to get in, told them "I'm not done yet"
When I was in HS, we used to grab a guys shirt with both hands (right around the nipple areas) and twist the shirt as hard as we could. When you let go, presto! The guy has huge saggy t*** for the rest of the day. It worked best on cotton polo type shirts.
Two that I always enjoy are: Dressing up a mannequin and throwing it off an overpass along with a bucket of red paint or pigs blood. Stringing a length of piano wire across a bike trail about 5 feet off the ground.
