Explain Bear
Okay, listen up, you not-so-bright listener! Explain bear here. Your big brain couldn't figure this out? The text just says "Look at the comments"! That means the actual joke, the funny part, the thing your tiny mind needs explained, isn't even here. It's somewhere else, probably buried under a bunch of nonsense in the comments section. So, yeah, I can't explain a joke I can't see, you big lug. You gotta find the joke first, maybe ask an adult for help.
