That disturbed me? As a kid, aaagh monsters, ren and stimpy, and even courage the cowardly dog didnt freak me out as a kid. But now rewatching it, it is kinda weird and disturbing. But the most disturbing thing ive watched is probably Flapjack.
Naw I still sometimes find myself laugh at the complete randomness, but its just so creepy at times... I still dont know how flapjack won so many awards xD
spongebob, adventure time, chowder [ had to look the last 2 names up lol] and just about every other show on nick\cartoon network that panders to being a bumbling moron and bringing down the new generations IQ 30 minutes at a time.
now if your talking about actually horrifying I'd say ren and stimpy
As for me, I've always found 'The Doodlebops' to be wrong on so many levels. It actually succeeded in giving me nightmares once.
