Tony Randall and Jack Klugman hated the artificial laugh track and asked ABC to ether remove it or start filming in front of a live audience. ABC initially refused, but to keep its stars happy aired this episode without the laugh track, as an experiment. At the end of the original broadcast Randall and Klugman appeared out of character to ask the viewers to write into ABC indicating if they liked the show better with or without the laugh track. The results came in roughly 5-2 in favor of running the show without it. ABC disputed the results, saying someone against it would be more likely to take the time to write a letter than someone who didn't. Nevertheless, ABC decided to change to a three-camera format in front of a live audience beginning with the second season. When the show went into syndication in 1975 this episode was still broadcast without a laugh track; however, ironically, a laugh track was added around the mid-'90s when the episode was shown on cable stations such as Nick at Nite.
This show was originally broadcast without a laugh track. This was because both Randall & Klugman hated the canned laugh track and they convinced the network to air this show without a laugh track to get viewer reaction. A voice over during the closing credits asked viewers to write to the network. Viewer reaction helped the network decide to film all the remaining seasons before a live audience. Ironically when this show is aired in syndication it now has a canned laugh track on it.
