To bring back that hard edge and controversy we seem to be missing lately, who or what would you like to remove from the planet, and why? Go on, be controversial, be outrageous, be devious, malicious and nasty. BTW - naming certain posters on MR is dull and obvious, so if you name the obvious contenders, you better come up with a new and interesting reason why!
My vote - David Letterman. The schtick was dull 20 years ago, it hasn't improved (or changed) since. I don't understand how anyone can think the same damn routine over and over is still amusing. It's like the audience is laughing because someone programmed it in to them 'David pauses and smirks - it's funny!' 'David pauses, smirks and the tip of his tongue pokes out - this shit is so funny you will wet your pants!' 'David says something and a drum kicks in - start rolling on the floor holding your stomach with laughter!'
Seriously, what kind of demented moron thinks this is still amusing? His guest interviews are ok, but I'd be much happier if he were conducting his half from orbit.
