My wife sometimes teases me by tickling my nostrils with her pinky when I’m concentrated watching something she doesn’t care about.
One time I crabbed her hand and shoved that pinky so deep her second knuckle was inside my nose. She was screaming her head off.
Haven’t been able to do that more than once after that when she forgot. Now she’s always on guard.
Too bad wizards aren’t real.
Although, if they were, they would definitely conjure some “nut grinders”.
