Same here :3 I thought about dropping all of the execution orders I got from their assassins in front of their door :3 I have at least 20 of them.
When I troll in Skyrim, it's mostly whilst playing as a thief ! For example, during that quest for the Guild when you have to infiltrate the Lumidor, I emptied all of Aringoth's safe and left a potato inside. I did the same while pickpocketing Nazeem from all he's got !
Haha, I always leave trollish items when I empty a safe. And when I was sneaking through the Thalmor embassy, I killed their informant (can't remember his name) and left his corpse in Elenwen's bed. A sort of tribute to Razelan's drunken rant while he was creating a distraction earlier.
