Johnny Carson back as a guest host would be great....bring back Ed too as the sidekick, and get Doc to play with Paul and the band....that'd be awesome.
I'd like to any one of the following guest hosts:
Jay Mohr Steve Jobs (yes, THAT Steve Jobs) Woody Allen Tom Hanks George Clooney Dennis Leary ...or Mike Meyers and Dana Carvey in full characters Wayne & Garth
Someone mentioned Wayne and Garth hosting in full costume. With Garth as Band Leader, of course.
I'd love to see them poke fun with the guests as well. For instance, have someone bring out Bob dole and Bill Clinton, only to have Dan Akroyd and whoever does Clinton on SNL currently come out with the real deals.
They could have some real imaginative fun with these guest hosts if they read this thread .
