 Only one episode, "The 1000th Show", was filmed in Seattle.As with "Cheers", most episodes were filmed on Stage 25, Paramount Studios, or at various locations in and around Los Angeles.The KACL callers' lines were read by anonymous voice-over actors during filming in front of a live audience, and during postproduction, the lines were replaced by celebrities, who actually phoned in their parts without having to come into the studio.
