American NagBap - contestents are nagged each week, judged on their response to the nag, and then voted off in a popularity contest that has nothing to do with their skills in any way.
The Nag - contestents are selected to team up with one of four Nags who then compete against each other to idenfity the "Bapuiest Nag". The contestents are then immediately forgotten.
The Nag Factor - contestents are paraded in front of a group of "expert" nags who feel that they need more media exposure. Contestents are nagged, they respond, they're eliminated, and no one really knows the point of the show, and yet, the audience is nagged constantly to watch.
Dancing with the Nags - this show could be subtitled, Nags Fall Down, Go Boom. Properly marketed, this could be the most successful of the lot.
