NBC's THE COLGATE COMEDY HOUR alternated guest hosts each week to keep things fresh and conquer CBS' Ed Sullivan in the Sunday night ratings. This episode from Mar. 11, 1951 (six months after its debut) found Lon Chaney present and costumed as the Frankenstein Monster yet never speaks a word during his two scenes, shot at the El Capitan Theater in Hollywood. The theme has Bud and Lou putting on a show for the USO, with a trio of dancers working up a sweat and opera singer Jarmilla Novotna cracking up opposite Costello. Things kick off with the ever popular "Who's on First?" before a sketch in which Lou cannot connect on a local call while the obstinate operator has no trouble with long distance hookups to Barcelona and Moscow. Sid Fields as Uncle Charlie suggests raising money at a haunted house where a fabulous treasure is supposedly hidden behind a secret panel, from which Chaney's Monster bops both Abbott and Costello before vanishing. Lon also pops up during the finale for 'Don Juan Costello,' again kept silent though this time he displays a few steps of his own. Though he would never again grace a show with Bud and Lou, Lon would soon do a dramatic take on Frankenstein for a 1952 episode of TALES OF TOMORROW. His makeup closely resembles Jack Pierce but one would be hard pressed to identify the actor underneath, who first played The Monster in 1942's "The Ghost of Frankenstein."
