All in the Family S07E15 - The Draft Dodger

It's Christmas and Edith. Archie, Gloria, and Mike are hosting Archie's friend Pinky for dinner. Things soon get tense when David, an old friend of Mike's unexpectedly drops by. When David lets it slip that he's a draft dodger, an enraged Archie attempts to kick him out of the house, only to be stopped by an impassioned plea to let him stay by Pinky, because it's what his son, who was killed in action, would have wanted.
