Hey Arnold!, Season 4

Stinky:
[telling his scary story] This here yarn of a horror is about the ever-frighting: Monkeycat. In the dingy laboratory of the despicable Dr. Mischief, there lived an old furry cat. One day, the cat snuck into the cage of a frisky monkey and got himself caught. Dr Mischief watched as the monkey and the cat began to fight, they became entangled together and that's when the evil doctor got his big idea. He cut off the monkey's head and sewed on the cat's body and invented...Monkeycat!

Gerald:
Monkeycat?

Stinky:
Monkeycat!

Gerald:
What's so scary about that?

Stinky:
It's a banana eating milk drinking horror monster, Monkeycat!

Harold:
[throws his pillow at Stinky's face] That's not scary! That's stupid!
