Ok? OK? - ( moderator, sorry to get really off track ) but where did that one come from?

Someone told me that it came from a guy called Otto Krause who used to be the QC man at the finish of the ford truck production line way back in the early days, - he used to inspect the chassis, and if it was good, he signed it "OK".

BTW, I think MINNFLYER gave the simplest logical explanation to the stick back question.
