The Jay Leno Show has aired four episodes already and we still haven't seen the racetrack NBC built special for Jay, on which top celebrities are supposed to compete in zero-emissions vehicles and (presumably) perish in fiery car explosions. But not to worry! The track will debut on tonight's show, with Drew Barrymore taking a turn behind the wheel. Also, next week: Bob Costas, Al Michaels, and Rush Limbaugh. [Live Feed/HR]
