In this archival footage, college sophomore Mark Katz takes his family pet to the stage of Late Night with David Letterman to show off his dog's unusual skill: playing the piano in exchange for liver. Later in life, Mr. Katz goes on to train politicians and other public people how to be funny in public and more than once in these endeavors, has used liver as Skinnerian tactic.

Note: Mr. Katz is particularly proud that the great David Letterman used his joke as the segment's closing "callback" line.
Ha! That was alright.
