Sam does not interact with the guest stars of the show as often as the rest of the cast, but he is featured prominently in several episodes. In one he throws casually dressed guest star Rudolf Nureyev out of the building in a fit of temper, mistaking him for a bum. Although he is forgiven by Nureyev, he is still disheartened because Mr. Nureyev (whom he believes is an opera singer rather than a ballet dancer) did not live up to his expectations. In another, he seeks out Zero Mostel - who he believes to be "a man of dignity", and thus, a kindred spirit - only for Mostel to literally mock him behind his back during his usual tirade. Similarly, Sam makes a bet with Kermit the Frog during the Elton John episode, demanding Kermit to explain ""WHY does he DRESS like a STOLEN CAR?"", and is forced to wear a flamboyant, albeit patriotic, costume. During the third season's Halloween episode, Sam confronts Alice Cooper. Railing against the audience and "indecency" and "low brow" humor, Sam calls Cooper a "demented, sick, degenerate, barbaric, naughty, Freako!" Rather than being insulted by these comments as Sam was intending, Cooper takes it as a compliment and thanks Sam, to which Sam despairingly retorts, "Freakos one, civilization zero."
