9.  Fighting Johnny Vincent --

Unlocks Chapter IV
Unlocks mission 'Stronghold Assault'
Greaser respect +100
Nerd respect +10

As soon as you have control, you need to start moving as quickly as you can.
You are on foot, Johnny is on a bike and he has a steel pipe to hit you with
as he passes by.  Your nerd friend Petey is on top of a stack of cars that
leads to the controls of the magnetic crane hanging above this makeshift 
arena, but the problem is that there are six Greasers standing between Petey
and the controls.  Arm yourself with the Bottle Rocket Launcher.  Run around
avoiding Johnny's attacks and target each of the six Greasers above.  The 
Bottle Rocket Launcher should take each one out with a single shot and clear
the path for Petey to turn on the magnet.  Once he has activated the magnet,
Johnny will lose his bike and his pipe and from that point on, its just you 
and him mano y mano.  His health bar appears at the top of the screen.  This
fight is about as easy as any other fight in the game.  Use your combos and 
he really doesn't stand a chance.  Finish him off and the mission is over, 
as is Chapter III.  To make matters funnier, you tell him you never wanted 
Lola in the first place and he can have her.
