Reality Television - ideas needed

[NiceTexasGuy]

This looks like the most appropriate forum for soliciting ideas of this nature.  Forgive me if I'm wrong and feel free to redirect me.

Let me start by saying I abhor reality television -- but that's the point, so does my character.  Nonetheless, he finds himself tricked or coerced into becoming a contestant - along with his ex wife.  They vow to rise above the pettiness and drama and backstabbing etc etc etc and not get caught up in it.  However, the producers didn't get to be producers of a popular reality show by letting the contestants think for themselves.

What I need are ideas for the show itself, and for physical and mental challenges which will put my (very conservative) character (and his very conservative ex) on a relatively even par with all the kids 20 years their junior.  The main theme I'm looking for is that the ex wife starts to enjoy all the attention from the younger guys wanting to get into her pants, and over time will begin to betray the vow she made with her ex husband on national television.  She'll tell humiliating stories from their marriage.  She'll reveal his weaknesses that give his competitors a leg up on any challenges they're in.  She'll drive him crazy as he watches her flirt with all the other guys.  (and girls?)

And the producers will make sure neither of them get eliminated.

I've seen a few episodes here and there so I get the basic idea, but what I would love is to hear ideas for challenges that can be played out, both by groups and by individuals selected for elimination challenges.

Suggesting a specific real "reality" show won't help since I'm not familiar with any of them.  I'm not talking about a talent search sort of program, but something more along the lines of Survivor - but not set in the wilderness.  I'm thinking a nice house with pool and hot tub, billiards and ping pong, a weight room and plenty of booze to keep the drama going.

Any help will be appreciated, as well as anyone wanting to participate in the games.  I originally intended it for two people (my character and his ex) but it could easily be played as a small group game too, with another guy or two flirting with the MILF, and the presenter also playing the part of the unseen producers.  Given the fact there's alcohol involved, the characters will have to be 21 and up, but not much over 21 please, except for the ex.

Thanks for reading ...

Probably Big Brother would be the closest fit - the idea of different generations together. Most located in a house are younger generations (Jersey Shore, Real World, etc.).
