Thought this was amusing xD
Hehe, I remember some of those, especially the Transformers one. That really was a messed up episode, but funny as heck. Especially the part where the chick tricks Rumble into turning himself into a tree. If you want a make a funny edit, watch the first scene and then cut it right after she says "ouch" and looks down, haha.
The thing that I think is missing from this list is the truly frightening "Cartoon All-Stars to the Rescue" in which a bunch of cartoon characters gather together in one cartoon to convince a boy to stop smoking pot.
Actually, speaking of drugs, there was an episode of The Littles that really freaked me out when Dinky accidentally ingested a hallucinogenic drug…seriously, it gave me nightmares.
