Aaahh!!! Real Monsters

'Aaahh!!! Real Monsters' is an American animated television series about adolescent monsters in training, developed by Klasky Csupo for Nickelodeon. The show ran from October 30, 1994 to December 7, 1997 on Nickelodeon's main United States cable channel.

The show focuses on three young monsters — Ickis, Oblina and Krumm — who attend a school for monsters under a city dump and learn to frighten humans. Many of the episodes revolve around them making it to the surface in order to perform "scares" as class assignments.

Watch the Watch (Season 4, Episode 4A)
While getting ready to do a scare at a hypnotist's show, Ickis stares at the hypnotist's watch and inadvertently gets hypnotized along with the hypnotist's intended subject - a loud-mouthed Car Salesman. Oblina and Krumm are mystified that whenever the word "human" is uttered, Ickis begins to act like the Car Salesman.
