Various Muppet characters or guest stars broke the fourth wall and acknowledged the use of the laugh track. In the fourth episode of the series, Kermit the Frog was asked by guest Ruth Buzzi if he felt a gag or routine was funny enough for the show, to which he turned to the camera and replied, "That's up to the laugh track." A season two episode featuring guest Steve Martin eschewed a laugh track altogether to support the concept that the show had been canceled that night in favor of auditioning new acts; the only audible laughs were those of the Muppet performers themselves.
