S1·E21 Bigalow's Last Smoke

Mr. Bigalow, a lifelong cigarette smoker, wakes up to find that his windows have bars on them and his door is sealed shut. A mysterious figure appears on Bigalow's television, informing him that he will quit smoking. Bigalow scoffs at this notion and reaches for a morning cigarette. As soon as he lights up, a deafening alarm sounds, demanding that he extinguish the cigarette immediately. Bigalow is subjected to various endurance tests and is further tempted to smoke when thousands of cigarettes materialize in the room, only to disappear. After being driven to the edge of sanity, he wakes up to find that he no longer has a desire to smoke. Believing that the whole ordeal was a dream, Bigalow reaches for a cup of coffee, at which time the mysterious figure reappears on the television screen, insisting that Bigalow now work on his caffeine addiction.
