Oh yeah, that is annoying. Since they aren't voted out they sometimes last a long time. Mostly they've been okay this show. I've also found that occasionally someone will grate on me, but in the end I end up really liking them because they are nice people. The cowboys for instance last season.
We don't watch any other reality shows. There's just too much yelling and drama. We mostly watch comedies and lots of science channel and national geographic. Terry likes shows about the universe and we both like geology (plate tectonics, etc). Animals are good as long as they aren't eating each other. Lol
