this thread is quite funny either way... but the dogs... the dogs win.
the best prank ive done was when i wired a radio to the ignition in my freinds car and hid the new radio behind the origonal radio in the dash. the volume was cranked up, but not too high, playing a mixtape of justin bieber, hannah montana, some rly bad folk music, etc. he didnt know what to do. and it was funny when he pulled up with justin bieber blasting through the car.
