Schindler's List. It's a hilarious film about a guy and his grocery list, but when he gets to the grocery store he buys all the wrong stuff! OMG!
So when he gets back to work it turns out what he did get, despite being completely wrong according to the list, everybody can have a party!!! Yay!!!
Oh and for some reason, I have yet to find the hilarity factor, it keeps emphasizing a red coat. Anyhoo, give it a try. Hilarious.
