With its future still undeclared by Fox, the comedy's freshman year closes out with a guest spot by Ben Stiller, who plays the trashy, shaggy former stepdad of Lizzie's ex, Eric, who still regrets losing her. But hope springs eternal after she agrees to attend Eric's birthday party, leading the slacker to seek out his platitude-spouting father figure for tips on winning her back. Sadly, the only thing Lizzie wants to repair is her hair after a faulty dye job turns her into a frantic, frizzy blonde mess with no patience for her current beau, the unhelpful—and hopeless—Steven.
