I see your point but I'll have to just agree to disagree. I can see how a person could take 12 hours to figure that out after being stuck on an island with the same people, watched by video cameras 7X24, for 39 days on an unusual diet. A lot of the stupid things that people do on Survivor, Apprentice, and other "reality" shows are a function of the format and environment. No, I don't think Ian was a rocket scientist but I don't think he's stupid, either. But I can see where someone else could think that.
"No, I don't think Ian was a rocket scientist . . ."
My use of "stoopid" is bombast; basically we agree.
