A LARGE bonus like the Apprentice game, where you pick who you think will win DWTS!
In Apprentice, if I keep Heidi as my Bonus pick, AND she wins, I'll earn 400 bonus points! For DWTS, the points wouldn't need to be that large though. (& you wouldn't need to give the option to change the Pick...since that might mean more work for you, Cinera. )
