Bill Parcells, clearly upset about the Dallas Cowboy's losing record, decides to find out from Bill Belichick what his secret is. So, Parcells travels up to a Patriot practice and asks Belichick, Coach, how is it that your team is so good? What's your secret?
Belichick responds by calling Tom Brady over. Tom, who's your father's brother's nephew? Tom answers, Why coach, that's easy. It's me. Belichick turns to Parcells and says, That's the secret, Bill. A smart quarterback. You've got to have a smart quarterback.
Thinking he's finally got all the tools he needs, Parcells returns to Texas and the Cowboy work-out. He promptly calls over Drew Bledsoe. Bledsoe! Who's your father's brother's nephew? Drew looks perplexed, thinks a minute and says, Coach, can I get back to you after practice on that one? Parcells (disgusted) says, OK.
During practice, Bledsoe calls over Julius Jones. Julius, coach just asked me the weirdest question. Who's your father's brother's nephew? Jones: Duh! That's easy. It's me! After practice, Bledsoe catches up with Parcells: Coach, I think I've got it. My father's brother's nephew is Julius Jones. Parcells (angry): No, No, NO! You idiot!! It's Tom Brady!!!
