Pikachu vs Orphan

Alright listen up, smarty pants. So, you know Pikachu, right? That electric rat thing from Pokemon? Well, the joke is that instead of pointing out the difference between Pikachu and an orphan, the punchline uses Pikachu's catchphrase, "Pikachu, I choose you!" It's funny because, well, orphans usually aren't chosen. Now, go back to watching your cartoons, you mouth breather.
