The Long John Flap

Who owns 'em now

Hawkeye's father sent him the long johns

Hawkeye Pierce

Hawkeye lends them to Trapper to keep him from getting sick (or to quiet him down)

Trapper John

Trapper looses them to Radar in a poker game.  Trapper had a full house but Radar had two pair of eights

Radar

Radar gives them to the cook for a complete leg of lamb.

The Cook

The cook gives them to Burns to keep from getting busted.

Burns

Burns gives them to Margaret because… um… he wants to get some.

Margaret

Klinger steals them from Margaret by using a bayonet to get them from the clothesline.

Klinger

Klinger feels guilty and afraid of getting caught with them so he turns them over to the Father.

Father Mulcahey

Mulcahey wears them overnight and turns them in to Henry in the morning.

Henry

Henry has an appendicitis attack and the surgeons have to operate - Henry doesn't want them to cut the long johns off him.  As a token of appreciation Henry gives them back to Hawkeye for saving his life.
