I love the intimidation of the WW II veteran--a Man's Man--and the metro-sexuals Jerry and George. Great stuff. A great episode showing the stark difference in generations. Elaine's father is old school; strong and gruff; Jerry and George are intimidated out of their skin.
Jerry and George hiding in the bathroom and being afraid to go back out and encounter the man is super. Wish this character had been in a couple of more episodes. He is right up there with Jack Klupkus but for entirely different reasons. "Pipe down chorus boy" is a great line and it stops George right in his tracks.
