I believe it was an animated collection of moral shorts. I watched it on tv in the late 70’s or early 80’s. The only part I remember is a misbehaving boy (I feel like he resembled Bart Simpson) is pushed into a museum display by his mother. It ends with him being a part of the display rowing a ship with other slaves.

I saw this in the mid 90’s on sundance     . It was a short that was about two elderly men that would get together and play like children. When they did this I believe they appeared as children. If I remember correctly one of them die in the end.
