You mean, there’s a scarier one than the one on Sesame Street??

Yes, but correlation is not causation.

I believe it's more due to overexposure to the concept. Knowing that you can deep fry the big bad evil guy in a fucking tanning bed kind of de-escalates the threat level.

Not sure on that one, but those meep meep guys did NOT make me less scared of aliens!

The Count was actually pretty scary [for a kids show] in the early years. They toned him down later, but in 1972 he was still frightening for kids.

Count Chocula probably helped.

I mean, is Mad Jack Churchill made less scary by the existence of Mr Bean, just because they're both Englishmen?

Not even close. A night stalking Vampire that will suck your blood out of your body. Versus a puppet?
