Calendar Thief

Alright listen up, chucklenut. This joke is based on a pun, which is a play on words. The dude stole a calendar, so he got "12 months"—get it? Like a prison sentence? It's funny 'cause you'd think he'd just get a fine, not a whole year in the slammer. And calling it the "worst joke ever" is just the cherry on top of this sundae of lameness. Maybe this is a bit too high level for you.
