Seinfeld bloopers

For you curious types, Kramer lost his toupee while puffing on a Cuban cigar that he got from George. You know , the same ones that burned down the cabin. (BTW, I saw this when Jason Alexander was on some rerun of Regis & Kathie Lee). Anyway, many of you will remember how he lit the cigar on Jerry's stove and then got lit up himself, screaming out the door. The take in question has him feeling some serious pain and screaming into Jerry's bathroom....I think he actually ran the water! The toupee was there to cover up the smoke machine that was attached to the top of his head. As far as I know, however, that hair IS real.
