Jack Gleeson, Alfie Allen Jack Gleeson, Alfie Allen

The cast of Jersey Shore or the Real Housewives franchise may seem too over-the-top to be real, but these outrageous characters are precisely why we watch. As Game of Thrones approaches its second season finale Sunday (9/8c, HBO), the cast reflects on which colorful series character could give Snooki or Nene a run for their reality money.

The overwhelming consensus is that Theon Greyjoy (Alfie Allen) is Season 2's breakout Westerosi. The former ward of Winterfell came into his own in rather dastardly fashion when he first unknowingly felt up his sister (whom he hadn't seen in over a decade), betrayed the Starks by taking over their castle and finally burning and mutilating two young boys and passing their corpses off as the youngest Stark sons. All this, and still he had time to get it on with a ship captain's daughter and a wilding captive. What a guy!

Check out the cast's picks for their favorite Game of Thrones character deserving of their own spin-off reality show:

Catelyn Stark (Michelle Fairley) I think Theon is doing pretty good at the moment. His life is pretty messed-up... It might be a bit X-rated at times, but I think it would be worth a view.  I definitely couldn't watch with my children though because that would be too embarrassing. I wouldn't want to know some of that stuff. I think his story would make for a lot of ... watercooler moments the next day, going, "Oh my God, did you see what he did?"

Robb Stark (Richard Madden) Theon! What Theon gets up to would be worse than Jersey Shore. But you can't help but watch it.

Jon Snow (Kit Harington) I think Samwell should have a spin-off. He's such a wonderful character, and John Bradley plays him so well. John and I have always talked about doing a spin-off with Jon Snow and Samwell like a buddy comedy.

Sansa Stark (Sophie Turner) Tyrion should have his own reality show spin-off. Or Tyrion and Bronn. They would be such a funny comedy duo.

Arya Stark (Maisie Williams) I think Bronn. When I was watching the show, I realized who his character was and how much it's got to do with how funny he is. He's obviously got a big story behind him, and no one really knows it. I think that's what's so likable about him, that he's not too serious, and you don't know much about him, so you got nothing to dislike about him.

Bran Stark (Isaac Hempstead-Wright) My spin-off series would feature Hodor and quite a lot of landscape shots, since he won't be saying much.

Jaime Lannister (Nicolaj Coster-Waldau) Reality shows need a lot of sex, so it would be Theon. It would be very entertaining to watch.

Renly Baratheon (Gethin Anthony) Elyas Gabel's character, Rakharo. I really want to know what happened on that horse-ride trip that he took and unfortunately did not come back [alive] from. Basically, if I could go on a road trip with Rakharo, that would be brilliant just to see what he gets up to. He speaks a different language and is a fascinating character... That or like some kind of reality TV show about government led by Tyrion, where he's laying the smackdown on every politician. On the Election Trail with Tyrion Lannister would be quite fun.

Margaery Tyrell (Natalie Dormer) The dragons definitely.

Ygritte (Rose Leslie) I love Tyrion. I love watching him. He is my favorite, so I think if Tyrion had a spin-off show, I'd be all over that. I'd love to watch that.

Gendry (Joe Dempsie) Definitely Theon Greyjoy. Never a dull moment in that boy's life; there's always something going on. And he's also such an interesting character because of what happened in medieval times when families would take a ward as a hostage. You're brought up by people, but essentially you have that internal conflict. You almost become part of the family. They're keeping you captive so your real family behaves themselves. It's a difficult thing to wrestle with. Theon today, in today's world, if he was famous, that would go completely to his head.

Lancel Lannister (Eugene Simon) This sounds really dark, but I'm going to say it would probably be Sansa. She starts with her story with these aspirations of marrying a charming prince and having little princes and princesses and ever constantly this kind of pure fantasy dream world. But the truth is, it would be an incredibly dark comedy to see how the reality show of her life actually panned out given what happens to her. So I think it would just be a hugely dark comedy to watch how Sansa's world suddenly descends into absolute misery. I have a dark sense of humor.

Irri (Amrita Acharia) I love Joffrey. I think he's amazing. I think I love him even more because Jack Gleeson, who plays Joffrey, is so sweet in real life.
