In the episode "Escape to Beer Mountain: A Rope of Sand", Henry was at JFK's party. When Abe got arrested by the Sheriff, he first watched in awe and heard Abe out, when he explained his reasons for buying non-alcoholic beer.

Albeit, this was only a painting and the clonefather never served an actual role in the episode.
