Ugh, yes. Still slightly creepy.I'll cop to being genuinely spooked by "And the Children Shall Lead" when I was a kid.
Masks has gotten several mentions but I'll throw that one in first. I genuinely didn't realize it wasn't appreciated as much as I enjoyed it.
I also enjoy Rascals from TNG and find it an interesting change of pace for the crew. I get why that one isn't popular though.
