Following the success of ``Scooby-Doo, Where Are You!,'' the lily-livered Great Dane and those meddling kids returned in a new series for more brushes with the spooky, this time rubbing shoulders with famous celebrities along the way. The show's duration was expanded to one hour, allowing for double the thrills, chills and corny laughs, as Scoob, Shaggy, Fred, Daphne and Velma solved crimes with the help of such guest stars as Don Knotts, Tim Conway, Don Adams, Phyllis Diller and Jonathan Winters. No team-up was considered too odd, with the Mystery Machine team even encountering long-dead comedy duo Laurel and Hardy, crime-fighters Batman and Robin, and the fictional Addams Family. Just as bizarre was the three, count 'em, three separate appearances by the Harlem Globetrotters among the show's 24 episodes. Zoinks, indeed!
