Mark: There is a basket of oil-soaked rags above a wood burning stove.
Ron Swanson: Oh, good thing I've got a fire extinguisher. Which, I can assure you, is totally up to your precious code.
Mark: Um, this says it should be recharged June of 1996.
Ron Swanson: Those dates are arbitrary. They're like those expiration dates that the government forces companies to put on yogurt and medicine. Observe. Watch yourself.
Mark: Yeah.
[As Ron attempts to spray the fire extinguisher, a small trickle of orange liquid runs out]
Ron Swanson: Okay, I'll replace this. Happy?
