Nothing, they're clean.

Ross

Ricky, did you wipe her wheels off?

Ricky

(Annoyed) Yes.

Ross

(Concluding) Well, they're filthy. It's just a matter of common courtesy.. (Wheels Sara over to a spot off the rug) When you come in the house you wipe your wheels.

Susan

Excuse me. (Answer the door. It's her doorman, Raymond, carrying a burnt box) Hello, Raymond.
