"It must be a Thursday. I could never get the hang of Thursdays." -Arthur DentWell, today is Towel Day, where we celebrate the one most useful item for an interstellar hitchhiker, and the guy who brought us The Hitchhiker's Guide to the Galaxy.
You'll be needing that towel, since that comet is due to hit any moment today, and probably save the Vogons a lot of trouble. Until then, it's imperative that we talk and drink over at The Skeptics' Circle, guest hosted by lame donkey.
Hat tip to sanguinity and Ithika for pointing out the entertaining Hitchhiker's Guide coincidences for those of us who haven't memorized the entire tome.
