This is my absolute favourite:
Homer: Okay guys, I've got a secret play I've been saving for the Olympics, or possibly the final four. And it goes something like this: [mumbles] Skinner, I want you to block out Carl. Moe, you can take Professor Frink, Homer you take Groundskeeper Willie... No way am I taking Groundskeeper Willie... Yes you are, are you a team player or not?
