1. Vigilante Wars. This may be stealing from a film, but people who had been hard done by with the justice system after their attacker got an apparently soft punishment can be reunited with the criminal who they are (within reason) free to humiliate whichever way they wish in front of a baying studio mob. There's only one catch: the criminal is given three chances to redeem themselves by doing something which could be so moral it would get the offender back into their good books.
2. Meet the Bigots. A Sacha Baron Cohen style where an apparently inoffensive student journalist from an obscure foreign country goes to the less open-minded parts of the UK and gently fishes for people to make offensive comments regarding race, religion, gender, sexuality etc. It wouldn't be as larger-than-life and over the top as Ali G, Borat or Bruno, it would be a lot drier and not all comedic as you could genuinely come up with some nasty, scandalous stuff. Maybe the opening scene should be "Clitheroe's only all-white taxi firm", White Star Taxis, where our character says to a driver, "Those Pakistanis, they're a top bunch of lads aren't they?"
3. East Meets West. A bunch of fundamentalist Muslims from Saudi Arabia and a bunch of Hollyoaks/TOWIE people who are basically all prostitutes swap places. Hilarity and violence across the world ensues.
