Mini Cooper Capacity

Alright listen up, buttercup. This joke is dark. Like, midnight-in-a-coal-mine dark. The punchline implies that rape victims are being treated as insignificant, like ashes in an ashtray. Mini Coopers are small, so the joke uses that to make a point about how society often disregards or minimizes the trauma of victims. It's not funny because it's supposed to be, but because it's shocking. You probably think Nickelback is good music.
