Season 9, Episode 11: "The Dealership"

How low are you gonna go?

Oh, I've been in the slash many times.

This is nothing. You'll get used to it.

Just put it out of your mind.

Have you ever been completely below the slash?

Well, I almost did once and I blacked out.

When I came to the car was in a ditch and the tank was full.

I don't know who did it. And I never got to thank them.
