Goat Simulator Glitch - Infinite air time + 'Mattress Madness' achievement

This is the biggest glitch I have found yet and it's pretty much game breaking. It lets you fly up in the air infinitely, at the same time doing stunts that are actually on the ground (50x treadmill stunt,..) and eventually unlocks one or more achievements. 1) Lick a car 2) Have it hit by the car or the truck, so it's flying beyond drawing distance of the game (maybe lower the graphics settings for this purpose) 3) With the tongue still attached try jumping off mattresses or fans 4) Keep pressing a direction key and your goat should fly up until you get massive points and achievements or crash the game by reaching the map limits.
