Origination of Green Slime - You Can't Do That on Television During its original run, the show was seen as one and the same with Nickelodeon, achieved high ratings and is well known for introducing the network's iconic slime (usually green). Likewise, when someone said "I don't know", green slime, a gooey substance, would pour on them from above. This prank was known as being "slimed." As with waterings, the sliming gag was used in almost every episode, especially from 1982 onward (a number of 1979 and 1981 episodes featured no slime at all, and slime is known to have been used on only one episode of Whatever Turns You On). #GreenSlime #Slime #SlimeTime #Nickelodeon #NickTV #Viacom #80sTV #90sTV #NickStudios #NickelodeonStudios #NickAtNight #GettingSlimed #Gack #UniversalStudiosFlorida #90sNick #UniversalOrlando #YouCantDoThatOnTelevision #Goosy #ThickSlime #Television #Nick #FamilyFun #FamilyTV #TVStudio #GameShows #KidsTelevision #CowMissingOnYouTube 📷: nickelodeon
