[A sixteen-year-old Marshall is naked as he goes to the drive-thru:]
Man: You're naked.
Marshall: I'm aware of that.
Man: You have 50 cents?
Marshall: No... Look, can I just have my coffee, please?
Man: Sorry, we're all out of trays and lids. Two tall guys just came through here a few minutes ago and bought 'em all.
[Marshall carefully balances the twelve cups of coffee on the Fiero's dashboard. As he begins to slowly drive off, Marvin and Marcus jump out and scare him, causing him to stop and the coffee cups to fall onto his naked body.]
[present:]
Ted: And that is the origin of Marshall's insane "No food or drinks in the Fiero, not even groceries" rule.
