"The Annoying Orange" was weird, and bad! Annoying as... well, the original internet series.
Not only was the animation and characters ugly, but "Tutenstein" was one of those weird "educational" cartoons. It followed some girl who was friends with an undead mummy. Also wasn't animated all that smoothly.
Lets be honest here, "The Magic School Bus" is a weird show with a weird remise. It's weird. I liked it...
Also that Canadian cartoon that was panned by everyone, "SheZow." That was one messed up and weird show. Surprised it was allowed... but then again, Canada lets a lot of things slide. I haven't seen it, but the premise itself is weird.
"Fanboy and Chum Chum," was not only a horrible show, but extremely weird. It was annoying too.
"The Butt Ugly Martians," was hideous to look at, equally bad to watch, and very weird. Why would that be a show to begin with? This too was a Canadian cartoon.
Sorry, but this was another show that was so bad, it was BAD. The, "Mega Babies" was disgusting in every way. It too was a Canadian show.
"The Killer Tomatoes" was based on a film, and was very strange. It had a girl who needed to sneeze to turn into a tomato and stuff.... it was weird.
"The Brothers Grunt" was a horribly weird and gross show. It followed ugly characters searching for their brother as they farted, burped, and grunted the entire time. Sorry, but this was also a Canadian cartoon.
"The Twisted Tales of Felix The Cat" goes beyond the original cartoon and is flat our weird.
"Action League Now!" started on the tv show, "Kablam" as a segment. It got to be it's own weird show using stop motion animation on superhero dolls. It was strange to say the least.
"Mr. Meaty" was a puppet based show that was entirely strange and weird. It was short lived, but fans swear by it being goof and not given a chance.
You could put my "Gym Partner is a Monkey" on this list. Why was there a show about a kid who had a gym partner as a monkey? Why?
"Courage the Cowardly Dog" was weird. Need I say more?
Anything from John K. is going to be a weird show. "The Ripping Friends" is no surprise to be on this list. It is very strange.
