Our 12-year-old Jacob is fond of saying, “RKO,” whenever someone provides biting commentary or a wicked respond.

I always assumed that he was just making a mistake and intending to say, “TKO,” a.k.a. Technical Knockout.

Trying to find out if my assumption was correct, I asked what RKO means.  His response, “Right Out of Nowhere Knockout.”

Hmm, but would’t that be RONKO?  Oops, there’s one more exhibit in the case “Jacob’s dad is sure getting old.” RKO!
