Nickelodeon lovers of my generation and younger, if you don't remember this show (I do!), you may not be aware of the origin of the beloved green slime. If that's you, prepare to be educated.
Whatever you do, if someone asks you a question you lack the answer to, don't admit to it, as you'll see in the second clip.
I'm all for Teen Nick bringing back 90s Nickelodeon, but don't neglect the 80s (yes, I know this show started in the 70s in Canada, but it was on here in the 80s in Nickelodeon)!
