When it first came out, I made my brother believe that "The Sopranos" was about our family because we're Italian and they always told us my great-great-great-grandfather was a mob guy.
I also told him our dad worked in "The West Wing." (it's very fun having brothers much more young and naive than you.) So whenever my dad goes on a business trip, my brother says, "Say hi to Donna (whom he has the biggest crush on) for me!" My dad still hasn't figured it out, and neither has my brother.
