Ko 

1)K.O. as in "knocked Out" can be used in life when someone is unconcious and also appears in fight games when there is a victor and the loser is K.O.

2)the dyslexic way of saying OK.

KO 

"KO" is the equivalent to the meaning & abbreviation of the letters meaning "OK" and was used on "Mork & Mindy", which is a t.v. series that had aired from 1978 to 1982. Mork is one of the main characters in the series, and an alien from the planet Ork. He would commonly reverse the proper order of human words and phrases that he spoke, by mistake

"Owie! Shazbot, shazbot, SHAZBOT! I stubbed my little toe when I tripped over the footstool Mindy, and it hurt!!! You didn't even ask me if I was KO!!!"

(Mindy replies)
"Oh, Mork! I'm sorry- did it hurt? I think you meant to say that I didn't ask you if you were "OK", on Earth we ask if you are OK if you hurt yourself, not "KO"!!!

***Proper credit must be given to the true comic genius of Robin McLaurin Williams (July 21, 1951 – August 11, 2014) R.I.P.
