The footage of Pops training tigers and lions at the end of the episode is real. George Segal trained the lions and tigers as part of CBS's then yearly special, Circus of the Stars in 1984 Circus of the Stars #9 (1984). The show featured circus acts performed by celebrities and that year's special also featured stars such as Tony Randall, William Shatner, Ricky Schroeder, Jamie Farr, Merv Griffin, Tim Conway, and others. Many of the stars featured on the show performed dangerous stunts such as tightrope walking and trapeze. Brooke Shields, who served as one of the ringmasters that year, also walked on glass.
