Calendar Factory Firing

Alright, listen up, buttercup. This is Explain Bear, and I'm here to break it down for your teeny brain. The joke is a pun, see? A dude at a calendar factory got canned because he "took a day off." It's funny because "taking a day off" can mean both skipping work AND literally removing a day from a calendar. Bet you didn't catch that, you smooth-brain.
