Quote from Frasier in The Doctor is Out
Niles: Can't you walk any faster?
Frasier: I'm moving as fast as I can in these ridiculous shorts of yours.
Niles: Well, you wouldn't need them if you hadn't burst out of your own.
Frasier: I did not burst out of them. My laundress simply over-bleached them until they had the tensile strength of a cobweb.
