GTA V - Bigfoot Easter egg

This is found on a main story mission, named Predator. You are basically in the helicopter, using the thermal sniper rifle. Proceed on with the mission up until the point where you are scoping down at the ground looking for the people. On the ground you will see a deer, and also a human looking creature (bigfoot) that is basically standing in one place. As you are scoping in, you can tell by its characteristics, that it is, indeed, BIGFOOT! As you get a better look at it, it will then disappear. That is all there is to it.
