PSYCHO DAVE:
Appearance does play an important part in being a Goth Comedian. As far as my own act is concerned though, much of the material and the way I present it is very dark. Psycho Dave is my alter ego, he is my Mr Hyde. Offstage I am a pretty quiet sort of person, Psycho Dave is the hidden, dark side of my psyche: he is a madman but does not know it - and this is the foundation for my Goth Comedy:  the comedy comes from the misguided belief that light is dark and dark is light - Psycho Dave is a mad stand-up comedian who believes he is the only sane person in the room (nay, in the world).
This is not a unique concept - remember The Munsters and The Adams Family......the comedy there came about from their belief that they were perfectly normal families and everyone around them was "strange" or "different", and their inability to understand the extreme reaction they inspired in "outsiders".
(A good example of this dark is light, light is dark concept of comedy is seen in the relationship between Maralin Munster and the rest of her family - Maralin is "normal" and "attractive", yet to her family and to herself she is a freak, she is ugly because she is not a monster).
This is the basis of my comedy premise - being dark and disturbed is normal, what scares me is the rest of the world's concept of normality (because I know these people are probably extremely disturbed and capable of doing me harm).

The way I perform is also important. From an early age I've been a fan of Universal Studio horror movies - I especially like the way the insane are presented, especially Renfield (Dracula's servant from the original Bella Lugosi movie) - his (hilarious) facial expression and the use of his eyes to convey insanity have been a big influence in the way I present myself on stage.
When I perform at venues closer to home I include my "Stuffed Mum" in the act She is a life-size facsimile of my "dead mother" that I push around in a wheelchair (hence the "Psycho" connection) - she is a bit difficult to transport when I'm performing outside Wales. She has now, though, developed her own career as a Princess Diana Lookee-Likey model.
I'd describe my act as "character based" and very theatrical.

Stand-up comedy, I'd agree, hasn't been a genre associated with the gothic scene (until now).
Gothic comedy has been available in the movies and on television for many years: The Adams Family and The Munsters, as I have already mentioned, the old Abbot and Costello Meets.....(various monsters) series, and not forgetting one of the best gothic comedy films ever made "Young Frankenstein". But this trend in gothic humour in the cinema stretches right back to films such as the original version of "The Cat And The Canary" (1928), and the early talkie "The Old Dark House" (1932). The studios were reluctant to make horror genre movies at this time without a strong element of humour.

ADAM MALTPRESS:

For me personally, it's appearance, a love of black clothes (being colour blind, black's the only colour I can match comfortably!) and not really wanting to follow a crowd.  From the off I just wanted to look a bit menacing and dark on stage.  It's a confidence thing - if people don't know what to make of you have an advantage over them, and at the start of my career I needed that.  As I got into more Goth music, started listening to heavier stuff, I just picked up on some of the culture.  I wouldn't go out of my way to say "I'm a Goth" - I'm me, and what I like, who I am, fits into the Goth category to some extent.  I like Marilyn Manson; but then again I like Coldplay.  I like Blake and Milton's writing, but then again I like Terry Pratchett.  I don't fit all the Goth stereotypes, but I fit Goth better than any other label, I suppose.

Everyone needs to laugh.  I think the stereotype of the non-smiling, nihilistic Goth is out of date - people choose to fit into the Goth category (or just drift into it) for any number of reasons.  There's comedy wherever you look, and Goth culture is no different.  From a personal point of view, the fact I fit somewhere into the Goth "box" doesn't mean that I don't see humour in, for example, my relationships, or in the world around me.

MATT WALTERS:
For me it's the style and the content.  The style borders on the grotesque, black clothes ,dressing long black clerical gear, a deadpan delivery with no trace of smiling. The content I would say has reasonably macabre touches and involves a lot of biblical references, conspiracy theories and paradoxical thinking.  My comedy is black comedy ( in the sense of being about dark, unhappy things) with a touch of the biblical and supernatural thrown in which makes it gothic comedy.

The cartoonist Charles Adams seems the classic example of goth comedy and the Adams Family have had a lot of success as cartoons, tv show and films. Tim Burton and the film Beatlejuice seems another example. The director Joe Dante offers made films such as Death Becomes Her and Gremlins.  What distinguishes these films and makes them gothic comedy is their supernatural element .  So goth comedy is black comedy with a supernatural element.
