I’ve got two, but my big one is the Foreman’s Blackjack. It used to be capable of being activated on any target. You’d get a melee attack animation and a loud THWACK, while the target’s current animation was reset to the default idle animation. It didn’t cancel their spells or anything. It was just goofy fun.
I don’t actually expect it to be reverted to its bugged state, but I’ll keep asking.
