It makes total sense since Sam obviously has her nerdy side too, she is quite good with technology. And she is clearly very very intelligent (even if she isn't book smart). And I think it would be a really interesting episode if her Dad's side of the family was just completely 100% normal (Sam is hilarious when she gets uberannoyed with nice normal people).

But I agree with @HeyPeople145 that its hard to picture a guy like Freddie abandoning his family. Getting a divorce is one thing. But it was very strongly implied that he just left and hasn't done anything to support either Sam or Melanie.
