You could always attach a block of frozen bait shrimp under the hood. It won't stink immediately, and if it's close enough to something hot under the hood, it'll be 2 or 3 layers of funky, and fast.

Ah, Craigslist.... LOL!

My buddy was living with this C word that would not allow him to talk to me (He as since moved on!) - Anyways, I posted an ad that he was a superintendent for a local Chicago Suburban park district and that he has 4 Zambonis for sale. I copied and pasted the specs from the Zamboni website and included some pics of Zambonis behind a fence. I tweeked the name of the "salesman" to sound like his name and included his phone number. I also posted it on Craigslist in MINNESOTA (Who the hell buys zambonis in Chicago) - Best part... $3000 takes them all and I will deliver. He had several calls that night (all Voice Mail), and a million calls the next day! His woman was so pissed because he could not keep his phone on because it would constantly ring, but he could not find the ad for a couple days! attached is one of the pics!

all you need is 2 safety pins and an alligator clip jumper about 2' long....
carefully pierce one safety pin through the turn signal wiring (hot lead) then take the second safety pin to the horn wire then simply connect the alligator clips and wait. the horn will honk every time the blinker goes on ( at first he will think someone is honking at him its great) (also works good on a marker light)
if you are up wheeling it will be hours maybe even days until they find out. this works great and is basically harmless it will keep a guy scratching his head for a while

We had a smartass at work that bragged about how great his new POS Hummer was so we saved about 25 large garbage bags of paper shreddings (over the course of about a month) and one day dumped out the bags inside the Hummer...filled the thing from floor to ceiling, front to back! It was so bad we had to push the rear hatch down HARD to close it. LOLOLOL It took him about 3 hours to clean it all out enough to drive home, and 2 years later he still has the crap floating around under the seats

Find a full size picture of an Ohio plate and photoshop a message on it using the regular sized plate letters/numbers. Print it and tape it to his standard plate. How often do you look at your license plate? If he gets pulled over, that's bonus points.

There's this stuff sold on line (google it with the correct spelling) called "Liquid A$$", and the smell of a few drop will make you want to puke. Get some, put a few drops on a small piece of scrap rag, and stick it down in the air vent intake in front of the windshield.

I think the only pranks I would actually do to a "friend" are the non damaging ones or easy to clean non greasy ones haha

During an Xmas party last year a few of us lit off one of them confetti party cannons the size of a wrapping paper tube in our buddies Chevy pickup. Shiny glitter, confetti and streamers all over and in everything. Then did the industrial plastic wrap around the whole truck a few times. It was one mess after another. He was a great sport about it.

Me and a roommate in college plastered a friend of ours car with cheap nasty porn magazine pages. It was even funnier when the campus police showed up at 3:00 am to ask him why. It wasn't funny for us when he almost turned us in. But he didn't have any witnesses anyway.
