I haven't done that...but I did do THIS in my mischevous college days...
A friend of mine lived in an apartment building with three units-and the guy next to him was one of those crabby old jerks that hated "all those damn college kids" that lived around him. We honestly weren't that bad (didn't really throw big parties or anything) but he was a real a-hole.
My buddy and the jerk both had the same cable box and remote on their TV...so we waited one evening till the neighbor fell asleep on his couch (which he always did) and went over to his front window. The TV was in plain view so we took my buddy's remote and ordered pay-per-view porn on the guy's TV.
About twenty minutes later we hear him and his wife yelling and arguing...he was saying "honestly, honey, I have no idea how that got on there."
Yeah, it was mean...
Classic! DD, here is an idea for you.
