I can't imagine anything but that Jake will be perfect for SNL! He's got the right sense of humour, and doesn't takle himself too seriously, and he's got the style *and* the looks...... They'll probably make him look really weird in some of the skits.
My main gripe, of course, is that this show doesn't air for the whole world to see it. I can only cross my fingers and rely on some kind soul getting it all out on YouTube or the like, so us non-Americans can join in the fun.
