There is a link circulating around several of the blogs I read pointing to some cartoon site. It is http://xkcd.com it is not rude (at least not the ones I've seen so far); the latest, which had me in giggles yesterday, is at http://xkcd.com/324 - note that additional jokey words or clarifications appears if you place the mouse above the drawings.

(Sorry, I've just remembered that there may be a specific area for posting this sort of thing, but one Cargo started it, and two I'm too lazy to go and check. I will not be offended if it is decided that my posting is in the wrong place and it gets deleted.)
