He is not sick.

Dr. Riley is throwing up. He obviously can't lecture.

You witnessed the spew? Or you just have his word for it?

I think I'm coming down with a little bit of the clap. I may have to go home for a few days.

Dr. Riley doesn't have a history of lying to me.

You said this is the fifth time he's missed a class this year.

- Either he's dying or he's lying. - I'll give you two hours off clinic duty.

Fine. I'll have Cameron do it. She loves inspiring the inspired.

- You'll do it. - Why is it always me?

Because the world hates you. Or because it's a class on diagnostics.

Pick whichever reason feeds your narcissism better.

I'm not doing it.

You're supposed to stop me. Renegotiate.

And you were supposed to keep on walking.

Sorry. Guess we both screwed up. Go on. Do it again.

I'll do the lecture for four hours off clinic.

Two. I know you'd rather spend a couple of hours...

listening to yourself than listening to patients.

Class starts in 20 minutes.

- Dr. House, there's a patient. - I'm outta here. Take it up with Cuddy.
