Ryan
It's blatantly obvious Ryan no longer likes participating on the show. He doesn't look like he's having fun anymore, he's not funny, and too be honest I think his mood is killing the show.
Colin's still trying to have fun, but the dynamic between Ryan/Colin was always the biggest draw to me. Without that the show is seriously lacking. I think they need to either cancel the show or replace Ryan at this stage. Jeff David or Johnathan Magnum would be good choices as a replacement. But if Ryan doesn't go soon I fear the show will suffer ratings wise.
