Give up? It’s Alan Arkin. According to our research department (a.k.a. “Google”), Mr. Arkin is the only cast member from The Muppets who also appeared on The Muppet Show (1976–1981). Check out this clip of Alan Arkin doing terrible things to a group of singing bunny rabbits circa 1979. To be fair, he was under the influence of one of Dr. Bunsen Honeydew’s potions at the time. (Also, it was the ’70s.) Arkin has another Muppet-related credit: a series of sketches on Sesame Street with his then-wife Barbara Dana. Here they are as Larry and Phyllis, making strange noises. Arkin’s role in The Muppets is listed as “Tour Guide.” He won an Oscar in 2007 for Little Miss Sunshine. We’re guessing he has a good sense of humor.
