I found this on Facebook, but it could be 30 years old. Not sure who the original author was, but the quality was very poor, so I re-created it in Excel. I did not change anything to keep it funny as intended. Of course, you should add a back loop in the Machine Learning box: an arrow pointing from the "Program" box back to the "Output" box.
