Christina Applegate in Samantha Who? by Karen Neal/ABC Christina Applegate in Samantha Who? by Karen Neal/ABC

This Monday, TV's cutest amnesiac may not just be getting a new time slot (9 pm/ET), she may be getting a new boyfriend, too. On the next Samantha Who?, dimpled Invasion dreamboat Eddie Cibrian guests as the contractor Mama Newly hires to redo her floors and, um, kinda invites to do her daughter as well. Wacky chaos ensues when Sam fibs that she's a hockey fan, and turns to her ex, Todd, for G-rated explanations of terms like "high-sticking," much to the chagrin of his new squeeze (played by poor Kiele Sanchez, for whom Lost might as well have been called "Get Lost"). - Ben Katner
