Astrid: Hey, I ran into a bit of a fire hazard so there's no tape yet.
Peter: What is that?
Astrid: You see that white tubey thing? That is a propane tank for Walter's hibachi. And that see-through blob over there? That is a gallon of ethanol.
Walter: Abner, why did you leave the propane tank there in the first place?
Astrid: Someone wanted to cook bratwurst.
Walter: Well, why is the ethanol there and not in the cupboard?
Astrid: Because someone wanted to use the ethanol to clean the hibachi before they cooked the bratwurst.
