In "The Staircase Implementation", an "apartment flag" is mentioned as a small blue flag with a coat of arms on it of a gold lion rampant on a field of azure on it. Flipping it upside down signifies that the apartment is in distress. In "The Roommate Transmogrification", Raj was given a lapel pin version. It is seen in a magnet version on the kitchen refrigerator which Sheldon has turned upside down when there was trouble. Also in the "Fun with Flags" broadcasts, a full-size with gold fringe can be seen behind Sheldon along with the American flag. A desk size version is shown by Sheldon while Leonard is signing the original Roommate Agreement.
