Wow, this is a pretty exhaustive summary of Chandler's Nubbin. It's amazing what people publish on the internet these days...
Chandler Bing's Nipples - Data processing executive Chandler Bing (Matthew Perry) on the sitcom Friends (NBC, 1994-2004) was endowed with not two, but three nipples. Because his "nubbin" (what he called it) was such a curiosity, when people learned of the third nipple, they asked questions like "What's it shaped like?", "Is there a hair on it?" and "Can you flick it?" Tired of such questions, Chandler got creative and told them "Pressure on the third nipple opens the delivery entrance to Narnia." Chandler finally had his birth anomaly removed [a "nubbinectomy"] in his late twenties, and is now "without nubbin." On the episode "The One With Phoebe's Ex Partner" Chandler dated an ex-girlfriend of Joey Tribianni named Ginger who had a wooden leg. After some soul searching, Chandler decided it didn't matter about her leg. Unfortunately, when the girl felt Chandler's "nubbin" beneath his shirt, she immediately freaked and pulled away from him him. An excerpt of the scene follows:
Ginger: Do you have three nipples?
Chandler: Well, y'know, two regulars ... [clears throat] and, uh, one that barely qualifies as a ... [CHANDLER resumes kissing, but GINGER pulls away and gets up from the chair] Uh, what?
Ginger: [gathering her belongings and putting on her coat) Nothing, y'know, I - I just remembered I have to leave.
Chandler: You, uh, you have [laughs] you have to leave, now? How come?
Ginger: Oh, well, it's nubbin [correcting herself] NOTHING, um ... y'know what, I'm, I'm, I'll see you later, okay. [GINGER leaves the apartment and shuts the door on CHANDLER, and as soon as the door is shut, she quivers and gets grossed out at the thought of CHANDLER's nubbin).
Actually, I thought the scene was much funnier than it sounds since the one-legged girlfriend is played by Sherilyn Fenn. (Audrey from Twin Peaks will always have a place in my heart.) And they don't mention the ending of the show, where Chandler belatedly "realizes" that his nubbin was the source of his powers of sarcasm.
