Personal experience:
As a 29 year old male, I have never met or spoken to anyone, male or female, who has the same interest in The Three stooges or classic comedy unless they are linked this or some other message board. I have classic rock friends, heavy metal friends, but not a single Three Stooges friend. So from my experience, species is more an issue than gender.
There are people with a casual Stooge interest I've talked to, which is fine, but not the types who know the names of the shorts or can believe I truly like Shemp.
PS: As for the silent comedy part of my comedy interest, you can REALLY forget it. As least people know who The Three Stooges are. At my desk in work, I have a Three Stooges picture, a Buster Keaton picture, and Laurel and Hardy picture, among other things. My former boss, who was 48 years old at the time, saw the Laurel and Hardy picture (from LIBERTY), and didn't ask who they were, but WHAT they were. Not just the comedians, but the art form itself was foreign to her.
