Q:

How do I make sure all the Teen Girl Squad girls die?

I am playing Strong Bad's Cool Game for Attractive People, and have the option of playing a Teen Girl Squad mini-game.
I know I have to set up the story the right way, using object at the right times so that all the girls die gristly deaths, but I am having trouble figuring out the order of things. I know using hairspray on a girl before they talk to the basketball player kills off one of them, and giving the basketball to the player kills off another, but beyond that, I am at a loss.
How do I make sure all the girls die?

A:

First, find the 4 hidden cards:

You will need the shovel (located in the room with the Poopsmith in the King of Town's castle) and the Black Metal Detector (located in the room with the fun machine in Strong Bad's house.)

Megaphone: Buried at the track. 
Book: Buried in Strong Badia
Candy Bar: Dig up the loose dirt by Marzipan's house and pour Total Load down the hole.
Car Keys: Use the shovel with the car in the area with Strong Badia, Bub's, the Snap Shak, and The Stick.

Then, use the following procedure:

Scene 1 (before the game)
  Use the car keys with Whats Her Face, and use the basketball with Cheerleader
Scene 2 (walking)
  Use the book with So and So, and use sunscreen with The Ugly One
Scene 3 (at the game)
  Use the candy bar with The Ugly One, and use the megaphone with Cheerleader.
