Does anyone remember the segment where there was a teenage boy and father that lived together and the father vanished shortly after he met with someone outside to talk about some farm business or something? I remember in the segment the son was crying because all he wanted to do was find out what happened to his father. In the same segment I think there may have been reports of the father resurfacing in another state or something at a bar.

Did the father just abandon his son for a better life?

Leonard Dirickson, here is an interesting thread (http://www.sitcomsonline.com/boards/showthread.php?t=116652) with some recent posts (that don't actually come to any conclusion, unfortunately!).
