What the next Indiana Jones film should be about!

Now that Indiana Jones 4 has officially gone into production, I have decided to waste my time by presenting to you my treatment of the story. Yeah, I know it will never get made, but I really have nothing better to do, so with out further ado, here is my idea for the next Indiana Jones film:

An elderly Indiana Jones sits down at the kitchen table and is about to pour himself a delicious bowl of Wheaties. He grabs the box of Wheaties and is stunned to find that it is empty. NO WHEATIES! What ever shall he do? Without haste he grabs his car keys, jumps in the car, and heads to the local Grocery Store.
He parks in his car in the parking lot, gets out and slowly but surely walks towards the grocery store. He grabs a cart, just in case he needs more food items, and makes his way to the cereal aisle. He reaches finally reaches the aisle, when to his utter shock and amazement he sees an elderly Nazi grabbing the last box of Wheaties.
"STOP!" shouts Indy.
"Vhat?" says the Nazi.
"That's my box of Wheaties."
"No, it's mine!"
"Not any more."
Indy take out his whip, swings it over his head, and lassos it around the box of Wheaties. With all his might he pulls the box of Wheaties out of the evil Nazi's hand and takes off running.
"Come back here!" shouts the Nazi.
"No, you come back here!" says Indy, laughing at his nonsensical comment.
"You vill pay!" shouts the Nazi.
The Nazi spots a shopping cart and pushes it in Indy's direction. Indy turns around, sees the cart coming and increases his speed. It looks like he's home free, when he slips on the wet floor and falls on his back. The force of the impact causes the box of Wheaties to fly out his hand and into the arms of the Nazi. The shopping cart is about to run over Indy, he quickly rolls out of it's path.
"The VHEATIES ARE MINE DR. JONES!" says the Nazi in a triumphant voice. He's about to walk to the check out lane, when he spots free samples of cheese. He takes a sample from the tray, puts it in his mouth and is pleased. Just then he feels a tap on his shoulder, it is an extremely pissed off Indiana Jones. He punches the Nazi in the face, which sends the Nazi flying into a cart filled with tomatoes. Indiana takes the box of Wheaties from the comatose Nazi and heads to the check out lane. He has triumphed. So ends this installment of Indiana Jones.
