1: The most hilarious line ever spoken in King of the Hill. Hank Hill said this in Episode 10 of Season 1. Why was it so great? Well first, can you picture Hank Hill using a blender? Second, a blender is not something you can just leave on, because it's only on when you hold down the button.
2: A bizarre excuse to step outside for a cigarette when you don't want people to know you smoke.
(FROM KING OF THE HILL)
*Hank and Peggy are in bed.*
HANK: Uh, I got to go do some stuff. I think I might have left the blender turned on.
*Hank gets out of bed, goes outside, and lights up a cigarette.*
