How to remove engine cooling fan clutch. Is it right or left hand threads? Easy way to tell!

Not all fan clutches are normal right hand threads! As in some of them are righty-loosey, lefty-tighty! So how do you tell? One of the guys I worked with showed me this real simple trick that'll work every time. Same reason why some big trucks used left hand thread lug nuts on one side of the truck!
