Having held military positions that required him to be, in his own words, "mean" and "tough," "the guy who makes you scrub the latrine, the guy who makes you make your bed, the guy who screams at you for being late to work," Ross decided that if he ever moved on from the military, "it wasn't going to be that way any more," "vowing never to scream again".
I can only imagine the terror that must have been Sergeant Ross. Making cadets clean the "happy latrines" and chuckling as he made them do push ups for getting it wrong. I'm pretty sure that along with never screaming again, Bob Ross never got another haircut either. Here's to you Sgt. Ross!
