Best of the Muppet Show: Vol. 4 (Peter Sellers / John Cleese / Dudley Moore)
This delightful collection of episodes fromThe Muppet Showcelebrates three British comic giants who rose to fame in the 1960s and early  '70s. Peter Sellers is right at home immersing himself in layers of costumes and  accents, portraying a gypsy violinist getting heckled by his kin and a sadistic  orthopedist (with Hitler mustache) tying patients into knots. (During Kermit's  ritual interview with a guest, Sellers says, "I do not exist. I had myself  surgically removed.") While actor-musician Dudley Moore's guest shot never quite  gets traction--the script is dominated by lame jokes about a music-making  machine threatening the jobs of the Muppets' house band--there's a funny jam  session featuring Moore on piano in a crumbling set. The John Cleese show is  best, with the lanky Monty Python genius outraged about having to work with pigs  and refusing to participate in cheesy Wagnerian opera.--Tom Keogh
