LOL...I thought old folks went to bed early?

An exclamation of enthusiasm or encouragement, as in You've said it really wellright on! This interjection has a disputed origin. Some believe it comes from African-American slang (it was recorded in Odum and Johnson's The Negro and His Songs, 1925); others feel it is a shortening of right on target, used by military airmen, or right on cue, theatrical slang for saying the right lines at the right time. [Slang; first half of 1900s]

You Thought???
Old folks???

Subjective IMHO....

In early industrial revolution era factories and workshops there was often a single power source (steam engine or water turbine) which drove a series of rotating shafts in the rafters. At each workstation, a belt came down from the overhead shaft to the respective lathe, drill, grinder, press, or other machine. The belts were generally flat leather belts. The workshops were noisy. At the end of the working shift, the foreman would go to the main shaft, and with a long stick, reach up and hit the belt sideways, "knocking it off" the pulley. That brought all the machines to a halt. To this day, we still refer to quitting time as "knocking off"
