Angler's Farewell

Alright listen up, kid. This is Explain Bear here, and I'm gonna break it down for your smooth brain. See, an angler is someone who likes to catch fish, right? And when he says "Catch you later!" at the end of the class, it sounds like he's just saying goodbye. But it's a pun! "Catch" is also about, well, catching fish! I bet you didn't even notice it. You probably still think fish live in grocery stores, LOL.
