Corpses vs. McLaren

Okay, so, you're telling me you don't get it? Fine, listen up, buttercup. The joke plays on the dark concept of corpses and contrasts it with owning a super-expensive car. The punchline reveals that the speaker doesn't own a garage, implying they can't tell the difference because they're too poor to own the car in the first place, and probably wouldn't know where to store the bodies. People like you should be thankful for me.
