Another brilliant prank that will mess up someone’s day can be done by waking him up to fart sounds. It’ll be the first thing he hears when he wakes up and he probably won’t forget about it the whole day. It’s also easier to prank people the moment they wake up because their level of unpreparedness is really high.

What you can do is wake up before your target. Check what time he set his alarm clock for then turn it off. Wait till the assigned time and then turn up the volume of your speakers and click away on the fart soundboard.

Fart noises will come blasting out of your speakers. They should be really loud so that he’ll wake from to them. I’m guessing that an initial look of uncertainty will be on his face followed by understanding and disgust.

If you’re really evil and you want to torment him further just carry around a copy of the fart sounds on your phone or tablet and keep bothering him with it the whole day. After his fart wake up call, hearing the same sounds over and over again should be tormenting.
