It's funny, the hardest thing to do is to make something look like it's fast, loose and improvised, and get somebody to laugh.
But it's very difficult, I can tell you I played the Czech Open a few times and it's very difficult just to go on to a scene where the course is prepared differently when the greens are fast and he's not used to it and they're hard as a rock and he's not used to it.
Hunger also changes the world - when eating can't be a habit, then neither can seeing.
