Who: Tommy Chong, Alfonso Ribeiro (pictured), Lea Thompson
How It Will Play Out: Nostalgia contestants rarely walk home with the top prize. (The only nostalgia winner has been Jennifer Grey, who won during the Fall 2010 season.) However, many of the "remember them?" type of stars use the show as a way to relaunch themselves into the public sphere. If there's one thing that is for certain, it's that DWTS is a great way to revive a career.
Prediction: Unless Lea and Tommy have serious moves, Alfonso will likely last the longest out of the three. If he can mix the right amount of charm and dance moves, he will likely make it to the semifinals.
