10 Shows From the '90s and Early '00s That Scared the Crap Out of You

Nickelodeon was really just doing whatever they wanted in the '90s, and "Aaahh!!! Real Monsters" is a true indication of that. The creepy cartoon show followed a group of monster friends learning to properly scare humans — a cruder "Monsters University," if you will. But "Aaahh!!! Real Monsters" was several notches more mature (yet, also immature) than Sully and Mike, and looking back at the series, we have to wonder how this passed the censors.
