I like this one, because I suspected it went like this:
Brewthunda lays in bed, a ceiling fan slowly turning overhead. He pulls out a knife from the nightstand, raises his left arm, and draaaaags the blade down his arm, blows the hair off the knife, and draaaaags the blade down his arm again.
He smiles and glances at his horrified wife. He turns, and points the knife at her. "Do you think this is weird?" he asks.
She shakes her head no, very quickly. "I SAID, do YOU think THIS is WEIRD?" he said, as the ceiling fan turns. She starts to shrink back. Brewthunda leaps from bed, and punches a mirror into pieces, ignoring the blood on his knuckles. "DO you THINK this IS weird?" he says again.
"N-no... no," she pleads. "I think it's a very good hobby... please, just don't hurt me..."
Brewthunda smiles and nods, and says "In a few days, I'll be going down the river...."
