Today you're marrying your fiancé Alexis. Everything's fine. The church is beautiful. Everyone's here except your parents, whom you didn't invite because they want you to marry your psycho ex-boyfriend Biff. But just as you were about to say "I do," Alexis had already put the ring on your finger when the church doors flew open and Biff was standing there with his parents, Lousie and Parker. Biff was wearing a wedding suit, and your mother was holding a new wedding dress for you in her arms.

Biff: Hey, I think your bride is mine!

Louise: Honey, what are you doing here? You're marrying Biff today, not Alexis!
