According to one interviewee in The New York Post, "Big-name comedians have what the Rolling Stones have for music groupies. It may not even be sex appeal; it's like laugh appeal. They're assholes." Comedians call such women "chucklefuckers." Funny!
Whether women swooning around comedians is actually a real phenomenon (the woman quoted "is not a groupie (she and [comedian Jeff] Ross had a real relationship)," the article helpfully qualifies) is difficult to determine from the article, although its general premise has been borne out by some research. One thing is clear, though: Guys win on this one.
