Quote from Monica in The One with the Morning After
Phoebe: "After applying the Waxine and linen strips to leg number one-" Monica: Did that. Phoebe: "Grasp the linen strip by its tab and pull it off in one quick, pain-free motion." [Monica pulls a strip and screams] Phoebe: Was it not "pain-free"? Monica: No, it was pain-ful! Oh, my God. They should call it "Pain-zine, now with a little wax." Phoebe: Well, the girls in the satin nighties on the commercial don't seem to think it's that bad. Monica: That's because their nerves are probably deadened from being so stupid.
