reality shows

i'm not a big fan of reality shows, but having watch 2 episodes of "The Contenders", i'm really hooked. this is one of the best reality shows i've watched, (not that i've watched many).. some shows are like somehow "fake", like some of the survivors series, where they plot against one another..i didn find that "real" enuff, but the boxers in Contenders are really fighting realistically, their blood, sweat, emotions, urge to win the cash money for their family..is so so real..

what other reality shows are there?

1. Survivor series
2. Amazing race
3. Bachelor and Bachelorette
4. Fear factor?
5.Apprentice
6.

What else? of all i only watched Fear Factor and survivor.. perhaps i can do with a prompt or 2?
btw, Contenders airs on AXN channel, singapore time 11pm every thurs..
