This may have already been asked, but if you could compete in any Reality Show, which would it be and why?

For me, I'd do Big Brother! It seems like the most fun and, sorry, but least physically demanding....I'm pretty weak, so I could handle this a lot better than say...Survivor. I can't sing, so AI's out. If I had a decent partner, I'd love to do Amazing Race, but I don't know who I'd do it with!!
