Welcome to Evil Week, our annual dive into all the slightly sketchy hacks we wouldn’t normally recommend. Want to cheat your way to free drinks, play elaborate mind games, or, er, launder some cash? We’ve got all the information you need to be successfully obnoxious.

The Lifehacker staff are all decent members of society with clean driver’s licenses and sparkling white teeth; we’re not like those scoundrels on Reddit’s Unethical Life Hacks forum. I’ve taken their shady tips and tricked them into bringing you 20 of the most morally questionable, legally dubious, often hilarious (but occasionally useful) hacks Reddit had to offer.

(Please don't do any of these horrible things.)

I don't have any of these pads, so I can't verify whether this sneaky crop spraying trick would work, but I don't see why it wouldn't.
