How can I Program Arduino to choose between options?

#include <LiquidCrystal.h>

int button=2

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(7, 8, 9, 10, 11, 12);

void setup() {
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 2);
  // Print a message to the LCD.
  lcd.print("I'm Magic 8 Bot!");
  // Setup Pt. 2 of LCD.
  lcd.setCursor(0, 1);
  // Print Bottom part of LCD
  lcd.print("Ask a Question.");

}

void loop() {

  if(digitalRead(button) == HIGH){
    // here, I'd like to have a number of different possible outcomes that can be read out on the lcd, but I can't figure out how to program a randomizer.
  }

}

Here is everything. Also, thank you for these salty comments, they give me a wonderful view of the community. Like I said in the first forum, I'm looking for a way to randomize options. In the code, I made a comment about it in the loop section.
