A is for Acceleration:

Its a big day at Choco Mountain. Not only are they giving away free Choco Mountain chocolate, but there is also a race! But there is a problem.

Luigi: "How do I accelerate?"

(Awkward silence.)

Luigi: "Please tell me how to accelerate."

(Awkward silence.)

Luigi: "HOW DO I ACCELERATE?"

(Waluigi comes over and puts some tape on the words above a gas pedal.)

Waluigi: "Just look here."

(Waluigi points at a gas pedal.)

Luigi: "Gee, thanks!"

(Waluigi walks back to his kart.)

The words above the pedal read:

XXXXXXXXXXXXXXXXXXXXXXXXXXXXX Acceleration.

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

(Note: The Xs are tape.)

Lakitu: "3, 2, 1, GO!"

Luigi floors he pedal, and in less than a second, he's off the mountain.

The tape peels off, and now the words read:

Experimental Ultra Light-speed Acceleration.

DO NOT PRESS UNTIL FURTHER EXPERIMENTATION!

Luigi: "Oh no."

The kart keeps going. In 2 seconds, its halfway around the world. In 4 seconds, its been around the world.

Lakitu: "Lap 2!"

Luigi goes around the world again.

Lakitu: "Final lap!"

Luigi goes around the world once more.

Lakitu: "LUIGI WINS!"

(Luigi's kart runs out of gas.)

Luigi: "What happened?"

Mario: "What do you mean 'What happened?'! You won the race!"

Waluigi: "WHAT!"

Luigi: "Thanks Waluigi!"
