Foreman: "Do you think I'm boring?"
Chase: "Yes."
Foreman: "You're saying that just to screw with me."
Chase: "Yeah! Why would you expect anything else?"
Foreman: "I expect House to pull my strings, I expect Cameron to make me feel better, I expect the new team to kiss my ass, and I expect you to be honest, 'cause you don't give a crap."
Chase: [thinks for a moment] "Yes. You're boring. That speech was boring."
Foreman: [sarcastic] "Thanks so much."

Chase: "You don't let other people's problems affect you. You don't let your own problems affect you, and it's the screw-ups that make us interesting. You're never out of control, which is good... and boring. Never losing control means you're never putting yourself out there, never pushing your limits. On the other hand, you do have a tattoo, so maybe I'm wrong."
