Explain Bear
Listen up, buttercup. This is 'Explain bear' here, and I'm gonna break it down for ya real simple. The joke is all about the words soundin' alike. "Two-thirty" sounds just like "tooth hurty," see? And since the joke is about a dentist, it makes a lick of sense. You probably go to the dentist and skip brushing, don't ya?
