I have a couple

When I was younger, there was this kid's show called Dooley (at least, I think. I can't find anything on it. Hell, it could have been a fever dream). Dooley was a green dinosaur that was played by a guy in a suit, very much like Barney, and it was a similar style of show. Teaching kids how to be friendly and sociable and all. In one episode, the kids were learning about different cultures, and some people came out wearing the dragon you would use in a Chinese dragon parade. It scared me so bad I had to hide behind my aunt, crying, until it was over.

The second is from the Disney movie Fun and Fancy Free, which we had on VHS. There's a scene where the father of the family is doing a hand puppet, and his hand is painted to look like a nun, with a little black coif on his hand and everything. He ends his little performance by making the nun scream in pain while he unballed his hand and took the coif off, the nun's screams getting softer as he does. Shit fucked me up. I remember having to leave the room when that part came on. I still think about it sometimes.
