@Olivier5,
You're just jealous. Your supposedly 'highbrow' humour is dull and boring. Stick at what you do best, smoke a gauloises and look into the distance trying to express your angst at the futility of existence and your own ennui.
A lot of people think they're funny, but there's only one way to find out. When you get a fee paying audience of 200+ strangers roaring with laughter at your stand up routine you know you're funny. I've done that, and I've done it over and over again.
You could never do that in a million years and you know it. Which is why you sulk all the time.
