Samantha Who? Episode 2.03 The Pill

After Dr. Andy (Tony Hale, "Arrested Development") gives Samantha pills as part of a clinical trial to help people with memory loss, she begins to regain multiple memory fragments -- all reminding her of how bad she used to be. But she discovers one pleasant reminder from the past that could have changed her life forever. Meanwhile, when Andrea and Dena are mistaken for a gay couple, Andrea tries to prove that she could hook up with a much hotter woman than Dena.
