1) Purchase a handicapped parking sign.
2) make a friend with a local police officer
3) place the sign on a pole that is stuck in a can of cement.
4) Place the sign in front of targets car in the work parking lot
5) have officer park behind target vehicle
6) tell target the cops are about to tow his car
7) target runs to car and sees police standing by
8) Cop makes target think he is parked in handicapped spot and getting a $500. ticket and towed.
9) After everything gets worked out...... Show target the video tape you just made of him pleading with the Cop and trying to explain how it wasn't a handicapped spot when he parked there.

Note* this works better if you know a cop that has a "tire boot"

 

Sry for such a delayed response.

File a police report

 

bet it can fit into really tight parking spots now.

 

And it can slip out alot easier too!

 

This depends on the car that the pranker has, and takes a little while to build up, but it is great.

Every day for a week or two, add about half a gallon of gas into the pranker's car (yes, give them free gas). They will start bragging about the amazingly great mileage that their car gets.
Then, get one of the long balloons that are used to make balloon animals; try to get ones that are as thin as possible. Fill it with gasoline, and coat the outside with a thin layer of lubricant. Push the balloon into the guy's gas tank. Keep a general idea of how much volume of gas you use, so you can put a few in his tank and fill about a third of it. As a result, the guy will be bragging about his magically effecient car, until it suddenly runs out of gas.

Use gasoline rather than water so that, if the balloon breaks, it will not do anything nasty to the engine. I do not know if the balloon will disolve in gasoline; it may be worthwhile to test.

 

Here's a classic that I've done to get revenge back for car pranks. Vaseoline under the wiper blades, and then write something on the window along the lines of "I'm a ****" or "Free rimjobs" or something else whitty. If said individual is lazy, they will use their washer fluid and wipers to clean the windshield. And then they find the wipers coated in vaseoline and have a HUGE mess to clean up.

 

ROFL!

 

A little bit of urine all over the car and a nice steaming poo on the windshield wont hurt anyone.

 

ZIPTIES: On his or her driveshaft....they will think that there is something horribly wrong with their car....pay an expert hundreds of dollars only to find that there are a bunch of zipties on the ds.

 

Throw some laxatives with some bird seeds at a flock of pigeons that are roosting near his car.

Wait ~30min, clap your hands, yell, and scare the ever living **** out of the pigeons such that they fly over his car and release their deadly ordnance.
