One of Nickelodeon’s first staple show was a program from the early 1980’s called ‘You Can’t Do That On Television’. One of its recurring gags was when people got slimed whenever they said “I don’t know”.
Funnily enough outside of the US (at least that was my impression as a German kid) Nickelodeon was first and foremost a company that made slime. You could buy that stuff here long before the TV channel made it over.

It has remained a trademark of the network ever since.

Even funnier is Nickelodeon bought the broadcasting rights to a Canadian kids program that did the slime gag. Slime wasn’t even “their” thing.
