House Amnesia

"Father: Get out of my house! Son: But this is my house, father. Father: Then get out of your house! Traditional joke."

During a heated disagreement, a character insists that the other character leave, only to be reminded by the other that he is already in his house. Alternately a character announces that he is leaving, and either before reaching the door or (more often) after leaving and coming back through the door says something to the effect of, "Wait a minute. This is my house." (Sometimes followed up by some variation on "You guys get out!")

Compare The Exit Is That Way. Unrelated to a certain jerky doctor.
