this led to problems, because not enough time was available for costume changes; Skelton was on camera for most of the half hour, including the delivery of a commercial that was written into one of the show's skits. In early 1952, Skelton had an idea for a television sketch about someone who had been drinking not knowing which way is up. The script was completed, and he had the show's production crew build a set that was perpendicular to the stage, so it would give the illusion that someone was walking on walls. The skit, starring his character Willie Lump-Lump, called for the character's wife to hire a carpenter to redo the living room in an effort to teach her husband a lesson about his drinking. When Willie wakes up there after a night of drinking, he is misled into believing he is not lying on the floor, but on the living room wall. Willie's wife goes about the house normally, but to Willie, she appears to be walking on a wall. Within an hour after the broadcast, the NBC switchboard had received 350 calls regarding the show, and Skelton had received more than 2,500 letters about the skit within a week of its airing. Skelton was delivering an intense performance live each week, and the strain showed in physical illness. In 1952, he was drinking heavily due to the constant physical pain of a diaphragmatic hernia and the emotional distress of marital problems. He thought about divorcing Georgia. NBC agreed to film his shows in the 1952–1953 season at Eagle Lion Studios, next to the Sam Goldwyn Studio, on Santa Monica Boulevard in Hollywood. Later, the show was moved to the new NBC television studios in Burbank. Procter and Gamble was unhappy with the filming of the television show, and insisted that Skelton return to live broadcasts. The situation made him think about leaving television. Declining ratings prompted sponsor Procter & Gamble to cancel his show in the spring of 1953. Skelton announced that any of his future television programs would be variety shows, where he would not have the almost constant burden of performing. Beginning with the 1953–1954 season, he switched to CBS, where he remained until 1970. For the initial move to CBS, he had no sponsor. The network gambled by covering all expenses for the program on a sustaining basis: His first CBS sponsor was Geritol.
