1: Find an apple tree.
2: Walk as far as you can away from the apple tree, while still having the "Search for apples" scroll menu option visible.
3: Select the option using mouse, while lookingat tree.
4: Tap W twice and hold to start sprinting.
5: While sprinting towards the tree spam the USE key until you get into the animation of collecting apples.
Result of this is you either find nothing or find apples many times in the course of a second or two.
This works roughly 1/5 times, and even higher when you get used to doing it.
