Wow. I last watched Pokemon and Zoey101. So, a high school with Pokemon trainers.

Doctor Who and Legend of Korra. I could try to imagine it, but I would fail. I really can't see how the two would mix. It's not any better if I use ANY TV show instead of live-action, because that would still be a combination of Legend of Korra and HIMYM which doesn't work because of age differences.

Mythbusters and the Animal Crossing movie....that would be AWESOME!

OHhhh my... Medabots combined with Person of Interest...
Hmmm I'm just trying to imagine Medabee in a suit and tie and kicking butt without his missile launcher... Actually, that might not be so far-fetched after all XD

Code Geass and the Walking Dead. 

I can't imagine the combination, to tell the truth. Maybe Lelouch would be the ruler of the Zombies and use the Geass to control them. =P

Dan Vs. and Dukes of Hazzard... this will SO not end well! *Imagines both Dan and Boss Hogg raising their fists to the sky and screaming, "DUUUUUUUUUUUKES!"*

Spongebob Squarepants and Swamp People. So basically Spongebob, but everyone talks in a southern accent, and the screen is always brown, so you can't see anything.

Alfred J. Kwak and Brotherhood. Oh man. The Irish Mob will never be the same.

Dragon Ball GT: Conan (Late night talkshow host Conan O'Brien.)

The Big Guy Theory? Or, even worse, gulp, The Family Bang.

Fish Hooks Meets I Didn't Do It.

I didn't do it would become far better, and Fish Hooks would be ruined. I really don't like that show (I didn't do it). Also, Fish Hooks is one of my favorite shows, so I'm extremely partial to it.

Some things were just never meant to blend. lol

My Little Pony: Friendship is Magic and The Big Bang Theory. That actually makes sense because Sheldon seems like he would because a brony.

Pokemon and The Walking Dead would probably result in this. I'm probably going to dream of this tonight...

Rocko's Modern Life and...the History channel or something. (I think I actually watched Adventure Time after Rocko, but AT didn't quite hold my attention for the entirety of what's been made of the series so far). I've watched the entire series of both Rocko and South Park. I must say Rocko is one of the few great things to come out of Nickelodeon...have you heard about its new Complete Series DVD set? I'm making it a prize for the end of this school year . South Park is a well-deserved pop-culture icon and I've ordered The Stick Of Truth from Amazon.

Rocko had an...okay...history-themed episode, but Rocko and the History Channel would not mix. I can imagine Heffer thinking that there were UFOs on Egypt and also thinking that Rocko is a dinosaur XD By the way, Heffer's seen Rocko "NAAAKEEED, with no clothes on". Maybe not appropriate for school, but a very underrated and hilarious scene nonetheless.

The last live action TV show I watched was Person of Interest, and the last cartoon I watched was Teen Titans. Those two shows combined would be pretty weird, because a group of superheroes would help adults prevent crime by using intel provided by a machine to predict imminent crime and prevent said crime from happening.

The last live-action tv show I saw was Doctor Who, and the last cartoon I saw was Spongebob. Those two combine actually seem like a cool show. Spongebob as the Doctor, and Squidward can be like the Master or something. Patrick will be Rory though.

The latest cartoon I watched was Uncle Grandpa. And the latest live-action TV show I have watched was iCarly. Because I would like to see this in a crossover, I am going to make a story.
  
The iCarly gang are losing ideas, and especially viewers. Because of the lack of attention, Sam becomes angry and throws a bucket of fried chicken to the wall. Her friends; Carly and Freddie, even have to fight her so she can calm down. However, that doesn't work out.

The bucket starts glowing and implodes, then transforms into a portal. Mystical creatures(Uncle Grandpa with Belly Bag, Mr. Gus, Pizza Steve, and Giant Realistic Flying Tiger) start coming out of the portal. Uncle Grandpa introduces himself to the crew of humans. Carly explains iCarly's downfall. Then it hits Uncle Grandpa, he comes up with an idea to get iCarly back to it's roots! The new era of iCarly begins

Uncle Grandpa commands Belly Bag to pull out a camera, even though Freddie has a personal one. They start filming the new episode. When Carly was about to pull out a Random Dancing! segment, Uncle Grandpa says that everyone has to lick Mr. Gus's meaty dinosaur toes.
Not to mention that it is a million years old. When Pizza Steve was about to lick Mr. Gus's toes, Sam eats him!

When the recording was finished, they upload the episode to the Internet. After 1 nanosecond, they episode becomes an INSTANT HIT! T iCarly gang thank Uncle Grandpa and his zany friends. Uncle Grandpa and his friends return to their original home. The end.

Wait, didn't Sam eat Pizza Steve?! OH NO!!
