Well depending on how much money you have laying around for a joke I have a decent one I did to an uncle. He would always prank me so on April fools day when I had a few bucks laying around a local gravel and dirt yard had a sale on manure. It was like $12 a yard. However they offered free delivery with any order of 4+ yards. I went down and purchased 5 yards. Here is the best part. They dump loads where ever you want and don’t ever ask for an ID. Anyways I gave them his address and paid an extra $15 to have first dump so at 5am a dump truck backed up to his drive way which is about 1/8th mile long and dumped 5 yards of horse shit blocking his way out. He had to use one of his riding mowers to move it all into the ditch and is still mostly there aside form the few loads he used in the garden! It’s a prank that was funny and can be useful if they have a garden!
Make sure your pals are passed out in the car and park it really close infront of a tree. Then step on the gas and honk the horn and yell very loud that ur going to crash waking and scaring the shit out of them and making them think that they are headed towards the tree you guys are parked so very close to.
Did it to my cousin 1 time and it was jus too great.
Sit in the bushes outside of the exit of ur HS, then when they leave... Pop out and shoot the driver in the head w/ a 12 gauge shotty. Trust me gets a good laugh every time.
