He was a member of the Seattle Seven. He likes to bowl. He'll have another Caucasian. He just wants his rug back. Or, at least, he's the basis for the guy to whom all of the above applies.
Jeff Dowd may look more like Seattle pot-lawyer Jeff Steinborn than Los Angelino Jeff Lebowski
Jeff "The Dude" Dowd is the real-life character upon whom the cinematic character Jeff "The Dude" Lebowski is based, and he was, in fact, a member of the Seattle Seven. And he'll be at tonight's Fremont Outdoor Cinema screening of The Big Lebowski, which is part of the two-day Seattle Lebowski Fest. (Tomorrow night is bowling.)
He doesn't look as much like The Dude as the Dude-doppelganger with whom I once shared a 'J' at a Radiohead show (and damn, I should've gotten a picture of that), but he offers a lot more in the way of bragging rights.
