Infinitum Jokes

The first orders a pint of beer. The second half a pint, the third a quarter ad infinitum. The bartender just pours two pints and says "sort it out yourselves."

Post an average joke, then inevitably a better joke will be added to the comments, steal that joke and post it, take that joke’s best comment joke and post it, repeat ad infinitum. Voila the world’s best joke guaranteed eventually.
