The first Survivor episode i watched was the season finale of the first season. I've seen every episode since. But I was in Canada on a trip over the summer and one of the channels up there was rerunning the entire first season in one day. When I first stumbled onto it, they were about four episodes in and I thought it was a spoof of Survivor. Every thing involving Jeff Probst seemed very serious and dark. Seemed like the show was taking itself way too seriously at the time. I'd watched a good 10 minutes before I realized it was actually Survivor.
Just funny to see how the show has changed through the years.
