Samantha Who?

When Sam feels her biological clock ticking away and realizes her desire to be a mother, she tries to probe her own motherly instincts by borrowing Dena's dog to find out if she's nurturing enough to care for and love it. Meanwhile, Regina attempts pilot lessons when she learns that Howard's late step-brother has willed them a plane, and Andrea continues to fuel the tabloid fires while she dates famous pro-basketball star Tony Dane.
