A talk show can only be as good as its guest. That means The Jay Leno Show can only get better than Pee Wee Herman's tornado of suck.

Wednesday's episode was a big step up from the previous night, thanks in part to Vince Vaughn's entertaining sit-down with the big chinned one. Couple that with some entertaining features like "Jaywalking" and the second "Green Car Challenge," and you've got a much better show this time round the track.

Part of that success has to do with the show's choice of guest stars, but this show stuck to what makes it work by introducing new segments that fit the old show's style and building on old ones.
