Quote from Francis in Malcolm Babysits
Stanley: "Lester." Francis: Looks like he was the janitor. How long you think he's been down here? Stanley: I'd say May of '85. [touches bones and licks fingers] Francis: You can tell that by tasting? Stanley: No, the date on the newspaper. Francis: Then why did you lick him? Stanley: How often do you get to taste a mummy?
