The point in a House M.D. episode where
Dr. Gregory House solves the puzzle and finds the one missing piece that saves the patient's life. It usually occurs the
minute a patient is about to die, resulting in House bursting into the room, making an incision, pull out a live animal (sometimes), and curing the patient of their affliction.
This was named for the Pilot episode and episode 314 (Insensitive) in which a ham
sandwich provoked the moment.
House Fan 1: "Why does he
keep looking at the hair behind her ear?"
House Fan 2: "Oh, this is it! The ham sandwich moment!"
House Fan 1: "Look at that, the cheap hair
color solution she used had chemicals that mimicked
hormones, which caused her to be sick."
