Buster Keaton was never a prima donna. He was a team player, from his earliest days in vaudeville with his family. When we see a Keaton performance, we see what those around him brought out in him. So when we see him in this delightful episode of "The Ed Wynn Show", we see what Ed Wynn brought out in him. And Ed Wynn knew how to tap into Keaton's comic genius.
The premise was simple enough. They set out to recreate Buster Keaton's film debut: the molasses bit from "The Butcher Boy" (1917). But while those of us who are familiar with "The Butcher Boy" will recognize the skeleton of the sketch, Keaton and Wynn put new flesh on it and breathed new life into it. Some of the freshest reworking comes in the way Buster and Ed made fun of the medium of silent films even while paying tribute to them. And the whole bit is funny in itself, and not purely in how it references familiar material.
I won't spoil any of it for you by giving it away. You can find it and watch it -- the entire episode -- at the Internet Archive. The Keaton bit is at the end, the final fifteen minutes. But the early part of the episode is worth watching as well, particularly for what Wynn did with his sponsor -- Spiedel watch bands -- and a pair of ballet dancers.
