Zig Zag was a Canadian children's TV series produced by BCTV (now Global BC) in Vancouver, British Columbia from 1980-1988. Among the hosts of the series were Terry David Mulligan, Susanne McLellan, Valri Bromfield, Mairlyn Smith, Bill Reiter, and Rick Ducommun. Norm Grohmann, Nicola Cavendish, and Ryan Stiles also made regular appearances on the show. One of the most remembered segments of the show was The Biff and Bart Show, which originally started out only as a two-minute "filler" segment, but as the years went by, it ultimately took over the whole show.
