For all you LOST fans out there, you're really going to want to think twice before watching this. It could ruin the season for you.

In the video below an actor auditions for what appears to be a Blue Cross Commercial. At the end of the audition the casting director, a big fan of LOST, checks out the actor's resume and realizes he recently appeared on the show's season finale.

Initially reluctant to talk about the show, the guy soon can't help himself. My favorite part of the tape comes just as he walks out of the room. Notice the way he gazes back at the camera as he begins to comprehend just what a colossal blunder he's made.
