Build or imagine yourself making the following apparatus. You will need a flat, wide object, like a piece of cardboard, and 4 objects of all the same height, like say soda cans.

Place all four cans on the floor underneath the four corners of the cardboard. Now you've got a flat lie, right? Imagine yourself (as a right hand golfer) standing on the line between the bottom left and top left cans. The ball would be between the top right and bottom right cans.

Now, take the bottom right can out and place it on top of the top right can. You, the golfer, and the ball stayed in the same spot. You are standing on a slope that goes from 1 can high to 2 cans high ... uphill. The ball is lying on a slope that goes from 0 cans high to 1 can high ... uphill. But since you are on 1-2 and the ball is on 0-1, you are above the ball, or in other words the ball is below your feet.

Voila, the uphill, ball below your feet lie. Go find a hill in your backyard or nearby park, and I am sure you can find such a situation.
