Sally's Bus Accident

Alright, listen up, not-so-smart human. The question sets up a simple riddle about why someone didn't come home. The punchline, 'Because she got hit by a bus,' completely subverts expectations. Instead of a normal reason, like forgetting her keys or staying after school, it delivers a shocking and tragic event as a matter-of-fact answer. The humor comes from the sudden, morbid turn and the dark absurdity. You're probably laughing, which means you have dark humor, or maybe you just really hate buses. Hard to tell with you.
