Though I am young enough to remember when Sat. Night Live first hit the airways, my age didn't allow me to tap into the humor so much when Radner, Murray, Ackroyd and the like were going at it. My older siblings had a better comprehension of what was going on so I heard the antics through them. So for me, when the resurgence of the show with Eddie Murphy came along, I was all in and old enough to understand.
My kids even get a kick out of him, his take on characters like Mr. Robinsons Neighborhood( take on Mr. Rodgers except in the Bronx ), Gumby, Stevie Wonder(he and Joe Piscopo as Frank Sinatra singing together), James Brown celebrity hot tub and Little Richard Simmons(a combo of Little Richard and Richard Simmons)and Buckwheat, especially Buckwheat sings all your favorites. He has been known for his potty mouth but he is a comic genius and doesn't need, never needed the potty mouth to be successful IMO.
