You know, there's something about Gottfried's delivery that makes me bleat out loud. I can hear him screaming this joke, and the thought of it cracks me up. His "Aristrocrats" (NSFW, Not Safe For *ANYTHING* - Consider yourselves warned!) is pretty darned funny the first time you hear it (does anyone have a video of the post-9/11 joke?)
(Mine was original humor, btw - I was pretty happy with it.)
