The nostalgia factor.Danica McKellar (with Val) is known to many as Winnie Cooper from The Wonder Years. Candace Cameron Bure (with Mark) was D.J. Tanner on Full House while 76-year-old Billy Dee Billy Dee Williams (with Emma Slater) is none other than Lando Calrissian from Star Wars.
Bringing the funny. We can probably expect NeNe Leakes (with Tony) and Drew Carey (with Cheryl) to add the funny factor.
