My sense of humor is the accumulation of all the things I have found funny. It's influenced by Black Adder, Monty Python, Charles Dickens, Mark Twain, Hunter S. Thompson, Tom Robbins, Salman Rushdie, (liberal) Dennis Miller, Terry Pratchett, and a homeless man I once met.
My ideal position for conveying humor is to be the passionately lunatic straightman. I find it hilarious, for instance, to expound with vim and vigor the value of redheads, or why meerkats would make great salesmen. Doubly so if I am convincingly deadpan.
Like Andy Kaufman, I find it hilarious to stretch a rant into "wow. He's really given this a lot of thought" territory, into "ok, I'm pretty sure he's just making this up. He must be having trouble keeping a straight face," then finally into "I have no idea if he was serious or not, but I'll never look at meerkats the same way again."
In other words, I have no idea, nor do I know how funny I am to other people.
