Swan Song amendment

I can't believe I didn't put Mr. Hooper from Sesame Street or Coach from Cheers on my Swan Song top 5. I literally couldn't think of anyone other than Peter Boyle or John Ritter who died mid-tv show, and both passed away doing less than their best work. But now that I remember these two guys, they absolutely deserve to be on my swan song top 5. I was reminded of both of these guys by this article. Picture courtesy of this website.
