I think you can more or less rule out:
1) Anyone from a different network.
2) Any obvious celebrity.
3) Any random element -- there's too much at stake with these shows to have a chicken picking.
I'm guessing that the "boss" is a collection of all the people who have been kicked off the show. That would fit the sense of karmic justice that people like on these shows. I could be off, but it's just my $.02.
