Orange is a Time LordThis Time Lord had a Time Lord companion and their TARDIS blew up while they happened to be eating a pear and an orange.
Orange is HaruhiShe recreated the universe after watching too much VeggieTales and Gorn back-to-back. Specifically:
Marshmallow is the son of the Stay Puft Marshmallow ManA piece of the monster survived and began to grow into a separate organism. The Ghostbusters found the small being and took it to headquarters. They feared the marshmallow child would grow into something as monstrous as his father, so they gave him a chemical that stunted it's growth. Given their connections with the supernatural, the ghost hunters handed Marshmallow over to a clan of unicorns living high above our world, where Marshmallow grew into the the sugary, optimistic little thing he is today. Eventually, his unicorn family sent him to earth to learn first hand about all the good and evil that occupied the mortal world. In this world, each object had a soul of it's own, and Marshmallow possessed the power to communicate with these inanimate spirits. But soon, he was captured by the Jigsaw Killer for his bubbly personality and over-optimism, and this lead to his first meeting with Orange.
There will be an Annoying Orange video called The Founding FruitsThe beginning of Angry Birds #11: Bring the Energy! (an episode of Daneboe's Angry Birds Let's Play) has a (most likely unintentional) Freeze-Frame Bonus showing Daneboe's computer screen. One of the files on his desktop is "The Founding Fruits v4_sm.mov"—likely an upcoming AO video. Accidental Production Foreshadowing?
Orange used to be an Exposition FairyCompare: "Hey! Listen! Hey!" "Hey! Hey, Apple!" Also, knife.
Marshmallow is related to RaritySince Marshmallow's mom is a unicorn and Rarity is part marshmallow... just think about it.
The universe exists in the Higurashi no Naku Koro ni universe
The Gourd has down syndrome
They will do a The Dark Knight Rises parody
The main characters are reincarnations of the Griffin family
Annoying Orange will make a crossover with Happy Tree Friends one dayNot only are they two of the biggest hits on YouTube, but both series depict characters being killed and revived.
Everything that happens in the TV series is Nerville's delusionHe is a man who talks to fruit, he acts like a cartoon character, and imagine how keeping the prices on Orange and co. outrageously high probably looks to outsiders?
The kitchen is actually Purgatory
