In 1979, a start-up variety program featuring primarily kids began airing on CJOH-TV in Ottawa, Canada. The show was titled You Can't Do That On Television and consisted of sketch comedy, music videos and live phone-in contest for local viewers. The show was well received and a national televised program called Whatever Turns You On immediately copied its format. Ratings were poor nationally and the new show would be cancelled after its first season. YCDTOTV would begin its 2nd season a year later in early 1981, again with just a local broadcast. That same year, the American cable network Nickelodeon would show interest in YCDTOTV and air 30-minute edited versions of show as a test run. It quickly became a hit and by early 1982, the network began airing the full season of 60-minute episodes. Nickelodeon began partnering with CJOH-TV on the production of the show as the series declined in Canada, but boomed in the US. Eventually, the show would go on to hold Nickelodeon's top spot in the ratings from 1984-86 and air daily on the network.
What made You Can't Do That On Television so popular? The show featured a great cast including young actors who would blossom into success stories. The slapstick comedy and sketches were great entertainment, but the real star of the show was a substance simply known as green slime. It became the staple scene of every episode. During a conversation between two cast members, one would ask a question to another. The gag was to get the other cast member to say "I don't know" which was the triggering phrase for the slime to appear. Another dousing prank would be anytime someone would say "water" in which they would subsequently get soaked. The slime became so popular that Nickelodeon would copyright it and own the rights to "Nickelodeon slime." The secret recipe for the slime mixture would be sought after more than the 11 herbs and spices used in Colonel Sanders' fried chicken. (It has been rumored to be some concoction of green Jello powder, oatmeal and possibly baby shampoo.) The slime would splatter its way onto other Nickelodeon show's like Double Dare and is still a tradition during the finale of the Kids Choice Awards.
