I would never want to be on a reality show. I don't even watch them. I would like to be on a gameshow though. I'd like to try The Moment of Truth...no knowledge needed just don't lie because people will find out anyways and you wont get the money.
Nope. But it might be interesting to go as one in the live audience. You get to see some things that TV doesn't show (like stuff during the commercials).
No, I wouldn't. I don't even watch most of them (except stuff like American Idol, So You Think You Can Dance, Dancing With the Stars, etc.) The only game show I might consider is Jeopardy, if I had a good enough memory for trivia.
I don't want the world to know my secrets. Some questions or things I would share with friends or people who personally ask, but I would never just share my life on TV!!!
