One of the (many, many) problems with the sketch was that it's impossible to parody something that's already a parody. There was nothing there that wouldn't have seemed out of place on the real show.
I think a much more promising approach would have been to have the guy desperate to be a part of the wackiness but have everything turn serious and tragic.
Of course, Bargatze's (and if I misspelled that, I have no interest in looking him up) idea of cutting-edge humor is that monologue with the obviously canned laughter and a re-hash of the Washington sketch, which was already something Carlin would have rejected as being too hacky in 1968.
