A pack of cigarettes

Two versions of Homer Simpson, one with an afro and one with a large blue afro, stand in a room with a pink and purple color scheme, each holding a cigarette and exhaling smoke rings that float between them. The scene shifts to a lab where a third Homer, in a white lab coat, stands with a cigarette, then turns to place a poster on a cabinet that reads "ONCE YOUR LUNGS GO BLACK" before the screen cuts to black and a glowing purple smiley face appears.
