Mary's Mother's Demise

Okay, listen up, you absolute walnut. You thought this was gonna be some heartwarming story, didn't you? About a mother dying of old age? Nope! This ain't that kinda joke. It's a trick question, my friend. It sets you up with some nice lady being good, and then BAM! Death by switchblade. The humor comes from that sudden violence and unexpected ending. You know, it's funny 'cause death is tragic but here it is delivered with a silly amount of stabs by a specific weapon. It's so absurd you're supposed to laugh. You might need a moment, because your brain's like, 'Wait, what?'
