A Family Of Talented Sons

So, let me get this straight.  Dad is either nine years old, or is so fashionably challenged that he wears enormous pants, no shirt and a sideways ballcap.  Mom is Peppermint Patty from the Peanuts comic strip (ugh, that hair!).  The first son is a rock star.  The second son is a baseball star (there's that pesky sideways ballcap again).  The third son is a cowboy WITH A $@&#ING GUN (Really, Mom? A gun?).  And the daughter has no discernible talent whatsoever. Yes? Okay, as long as we're clear.
