Al: I hope they didn't get his mucous cup.
Harry: What the hell is a mucous cup?
Al: Well, it's an earthenware goblet from Africa that's used as a spittoon for excess phlegm.
Tim: You sure seem to know a lot about a mucous cup. Were you around the crime scene eleven or so this morning?
Marty: Yeah, Al. Everybody knows you always dreamed of owning a complete set of mucous-ware.
Al: No matter how much I covet a mucous cup, I would never steal one.
