The infamous “Friends” character Ugly Naked Guy inhabits the apartment across the street from Monica’s (Courteney Cox). Although our favorite friends mention the character throughout the first five seasons, he only appears in the flesh (and only from behind) in two episodes. Ugly Naked Guy is introduced in Season 3, Episode 8, “The One With The Giant Poking Device” (via IMDb). In the episode, the six friends fashion a long pole out of chopsticks they use to poke the man’s stomach to confirm he’s alive. However, only Ugly Naked Guy’s torso and arms are visible.
The character returns in Season 5, Episode 14, “The One Where Everybody Finds Out” (via IMDb). Ross (David Schwimmer) learns Ugly Naked Guy is subletting his apartment. Hoping to gain an advantage over the other applicants, he devises a plan that involves him showing up at Ugly Naked Guy’s, with the character greeting Ross at the door. Ugly Naked Guy’s bare shoulders are visible to the audience, and he’s seen holding a monster-sized beverage. Later, the gang spots Ugly Naked Guy hanging out with a new friend: a naked Ross. The 1999 episode marks the last appearance of the character. Although Ugly Naked Guy is visible in these two episodes, “Friends” viewers never see his face. He is also mentioned in additional episodes, but doesn’t physically appear.
In 2016, Huffington Post senior staff writer Todd Van Luling’s chronicled his long and arduous quest to uncover the identity of the uncredited actor who plays the character. It was rumored that Michael Hagerty, who plays apartment superintendent Mr. Treeger was also Ugly Naked Guy, but Van Luling debunked the theory. Luling finally learned the actor who immortalized Ugly Naked Guy is Jon Haugen.
