It's the one mystery that the creators of Friends failed to answer during the entirety of its run. What does Ugly Naked Guy really look like?
You remember Ugly Naked Guy right? The nude neighbour lived across the street from Monica and Rachel's apartment and was a running joke throughout the series. He even made two on screen appearances. Once in season 3's 'The One With The Giant Poking Device' and the second time in season 5's 'The One Where Everyone Finds Out'.
Fans will remember that in the second cameo he even managed to convince Ross to join him in his disrobed lifestyle.
However we never got to see his face on screen. So we were never able to confirm if he was indeed as ugly as he was naked.
Luckily for us, the good people over at The Huffington Post launched a year long investigation to track him down.
IMDB credited the role to Michael Hagerty who played Monica and Rachel's superintendent Mr Treeger on the show but it turns out they were wrong.
It turns out the part was actually played by a man named Jon Haugen. This is what he looked like when he appeared on the show.
We know weird, right? Neither naked or ugly for that matter.
Haugen told The Huffington Post that: "there’s only one Ugly Naked Guy, man, and that was me.’
He added: "I wasn’t really expecting them to call me back for me to do it again."
"It was the best time in my life."
Haugen also revealed that he and Schwimmer weren't really nude when they filmed that tea and mini muffins scene.
"We were just in boxer shorts and they made it look like we were naked."
That's a shame, but good to have the truth out there. So there you have it folks. Ugly Naked Guy wasn't actually ugly at all. Do you feel cheated?
