Nothing lovable about the original, it was always a freak cartoon. Its how cartoons died in the 90s.
Original? Yes. Adult Party? Yes.
Ren Seeks Help is terrible. The original Ren & Stimpy was actually quite lovable. - redhawk766
2 Regular Show

Do you know why this is a creepy cartoon. BECAUSE OF THE CHARACTERS AND THE JOKES THAT THEY LOOK VERY WERID AND NOT APPROPRIATE. I swear Cartoon Network, why did you put a show about two morons that work in the park and go to strange adventures that were full of drugs and porn jokes. Well, that happen to me that I watch the episode where two guys were planning for a movie night and the electrically had created zombies so they can ruin the movie. Just, what the heck why everybody wanna to show it like that and ban parents from children. Ignore this cartoon and watch something better like MLP, fairly godparents, SpongeBob, and avatar.
It’s slightly inappropriate for small kids, but it’s still an awesome cartoon. - PageEmperor

I suppose different countries have different minds on cartoons. I was allowed to watch this when I was little.
USA (Where the cartoon came from): Any cartoon that looks sexual is not appropriate for kids.
UK/Europe: We are not prudish like America.
Japan: We made Beauty and the Beach, gory game shows.
How many kids in this century would have even seen this on television
