What are some really good pranks?

Question

And I mean for everything! Sleepovers, getting back at an enemy, mean brothers, ect.

Answer 1

ok, you need 2 people for this, and you need a hill. and 2 cars. hell, its a bit difficult.
you and your accomplice need to tail your victims car, and then wait until he/she stops on a downhill slope (prefferably if theres a busy road ahead). and you need to have one on one side, and the other on the other side.
then, you slowly start reversing up the hill. your victim will think they are drifting down the hill and will be slamming on the brakes and shitting themselves.
its hilarious, ive done it:)
