Ugly Naked Guy (Jon Haugen): an obese tenant in the apartment in the building across from Monica's apartment—who frequently, perhaps invariably, is naked with the drapes open—so the gang is frequently commenting on his activities—playing cello, wearing "gravity boots", etc. He is first mentioned in the second episode of the series, but only appears twice: first, his belly and an arm are shown in "The One with the Giant Poking Device"—in which he is being poked from across the street by the gang (who think he is dead) with a long device made from chopsticks; second, a rear view of him from head to waist is shown in "The One Where Everybody Finds Out" (his final show)—in which he is moving out of his apartment and Ross tries gets the apartment by ingratiating himself with Ugly Naked Guy by cavorting with him in the nude. (In "The One with the Flashback", it is learned that he used to be "Cute Naked Guy", but then, in 1993, started putting on weight.)
