1. Find an apple tree that allows you to stay crouched while searching for apples
2. Do an action for searching for apples.
3. Wait until the final part of the animation as the left arm comes up for that final time
4. Hit F repeatedly as quickly as possible

The effects are that your guys won't likely move, but you'll see multiple attempts being used up to harvest apples.

I also want to note something. Using this method to gain extra apples, in the new experimental nearly always causes a health glitch for some reason if your inventory is full and you have an apple in your hand and are still wailing on the 'F' key. Maybe figuring out why this glitch works will knock out 2 birds with one stone? I speculate the health glitch, where it says you are stuffed and are suddenly hungry and thirsty even though you've been eating), is due to the same mechanism as this one with trying to eat food and latency.

I would be willing to make a video on the apple glitch if need be, should be easy to reproduce.
