You Can’t Do That On Television is a sketch-comedy TV series that was made in Canada and aired in the U.S. on Nickelodeon in the 1980s. The show starred character actor Les Lye, who played all of the adult male roles – and there were dozens of them. Abby Hagyard played all of the adult female roles. At least five children appeared in each episode, and they always played themselves. Some of the children were on the show long term and appeared in many episodes over the years (such as Christine McGlade, Lisa Ruddy, Alasdair Gillis, Adam Reid, Vanessa Lindores, and Doug Ptolemy) – others appeared in only a few (such as Alanis Morissette, who appears below in the episodes “Pop Music” and “Enemies and Paranoia”). The show portrays many of its adult authority figures as worthy of being mocked, whether it be because they’re incompetent, evil, corrupt, or power hungry. Anyone who said “I don’t know” would have green slime fall on them, and anyone who said “water” would have water fall on them. The series was created by Roger Price, who wrote the script for every episode.
