The producers of Samantha Who? are hoping that you won’t forget to watch this: has learned that Timothy Olyphant (pictured) will guest-star in at least one episode of the ABC comedy about an amnesiac (Christina Applegate) who’s trying to turn her life around. The former Deadwood sheriff will play Samantha’s wealthy boss, who just might want to make her his own personal Employee of the Month, if you catch our not-so-subtle drift. The episode will air as early as next month.
