Secret Laugh Mode

It's good to see more hidden stuff in the games. It's even better that we manage to find it. ;-)

There are three duck quotes in this game, they all say the same thing:
"Any-one for Peking Duck?"

The first time it is whispered (you have to listen very carefully to hear it); the second time it is said by a guy with a Chinese accent; and the third time it is said by a woman.

There are many ways to get the quote:

Pull the trigger at the start of any mode except Duel of Wills, and Hotel.
Pull the trigger at the end of Duel Of Wills.
During the quote: "I know" (Who Knows award).
During the Extra Ball animation.
While getting a 'Scene Bonus 2,000,000'.
Anytime the ball is in the Battle Field popper.
 
The trick is that you can only get the quote once from each physical location on the playfield: Side Saucer, Start Scene and the Battle Field Popper. Also make sure you don't have Mongol running, as pulling the trigger will end that mode (awarding 3 million).

To start Laugh Mode, you must have heard the quote said by all three people. The easiest way to do this is:

Start a scene (at Start Scene), and pull the trigger.
Shoot the Side Saucer, and if Khan is not lit, you'll get the 2M Scene Bonus. Pull the trigger again.
Shoot the Battle Field, and pull the trigger before the ball is popped.
Once you have heard all three quotes, start a scene like you normally would, but instead of starting one of the regular five, the display will say:
