Robotech: Battlecry (although it could apply to any game with escort missions):
Commander: Jack, I want you to escort this slow, flimsy plane through the enemy infested canyon.
Jack: Pardon me if I'm out of line, but can't we just go around the enemy infested canyon?
Commander: I'm afraid not. That plane is carry a package that was sent by Fed-Ex overnight delivery, and we wouldn't want to to be late!
Jack: Fair enough. Why don't you just give the cargo to me?
Commander: That would be too easy.
Jack: What?!
Commander: You heard me. If you can't do this, then you won't survive the final boss fight.
Jack: Are you implying that I'm not the best pilot in the skies?
Commander: No, I'm telling you that you're not.
Jack:
Commander: Good, now let's get going!
