Didn't see that one coming!

Survivor has been pretty ho-hum so far this season, but it kicked into high gear tonight.

Alex, the Harvard-educated know-it-all, was so convinced that he was facing eviction that he played the immunity idol to save himself at tribal council.

But, after the votes were read, he discovered that NO ONE had voted against him!

Instead, the rest of the tribe out-witted him, making him feel paranoid enough to needlessly use the idol, then turned around and voted off his ally Edgardo.

I guess this is just another lesson on the power of paranoia, no?
