When your on the third level with Lisa go to the boat by the casino go
  off the ramp and around the boat toward the Springfield's Hollywood.
  On your right you'll see a krusty glass break and go on the ramp once
  you get on the boat drive to the right and you'll see a box connected
  to a crane go pass it and the take a left get out of the car and go up
  the stacked boxes. Once you get up those youl well have to jump onto a

  is a really fast car. Getting a blown up car by the bowlarma with lisa
  go into an alley way put a car you should get from someone driving put
  it under the thing that stops you from going and then goes back up it
  will it a couple of times and then it will blow up go by and press y
  if it tells you to if it doesn't you did it wrong. The car goes really
  slow because it blew up.

  

To skip a mission,  you have to fail a mission 5 times and then
  in the menu you will have the option to "skip" sometimes you
  will have to fail a mission 6 times. It's common sense if you have

  same as here! NOTE: THIS DOES NOT WORK ON THE LAST MISSIONS FOR ANY
