the brother to the amazing bassist of The Academy Is.., Adam T. Siska, better known as Sisky. He was on Survivor Micronesia and made it pretty far. He found a fake immunity idol and thought it was real until he gave it to Eliza to use and Jeff said it was fake. Jaon Siska=total domination. By the way, he is uber sexy!
Jason Siska pwned at Survivor, but got voted off because he didnt make any alliances.
