"Sincerity is everything. If you can fake that, you've got it made."

Looking for a link for that old George Burns joke -- I needed to add it to the "in the comments" update to the first post of today -- I turned up this old Ask Metafilter page looking for the most intellectual jokes:

Jean-Paul Sartre is sitting at a French café, revising his draft of Being and Nothingness. He says to the waitress, "I'd like a cup of coffee, please, with no cream." The waitress replies, "I'm sorry, Monsieur, but we're out of cream. How about with no milk?"

Much more at the link, of course, and, if we're lucky, in the comments.
