take pity on me, for I am hungover...

Has anyone heard that Bill Hicks skit, where he was talking about the advertisement in the US back in the days of the 'war on drugs' campaign (when they didn't have a "war on terrorism" to be concerned with) Where he was saying that there's a wino, dressed in a white singlet and trakkie daks, holding an egg up to the camera and sayign "This is your brain..." cracking the egg into the pan and frying it then saying "This is your brain on drugs"
... or something similar...
The thing that stood out was Hicks saying "I have taken trips where I saw aliens come down out of the sky and give me and all my friends chicklets, but I've never, EVER, looked at an egg, and thought it was a brain."
