We've had some truly great heads on Shirty over the time that we've been doing this. It's really been an honour meeting some of these folks who Shirty - through it's mystical powers of Shirtentology - has animated.

By today's head might be the pinnacle of the peak; the top of the best of the number one greatest heads on a shirt since the dinosaurs created heads and shirts to frolic without sin in the Garden of Iran.

And that's not because this is the Shirtmaster's first head-on-a-shirt since Frank went on vacation.

And it's also not because today's addition represents some grand statement, prolific point, or awesome observation.

It's because today's Daily Shirt is the rare combination of nerd and 'playa.' Yup, the man who gave us the Theory of Relativity was also something of a ladies man in those days, and a bit of a dirty dog at that (dude did, after all, marry and pop out a kid with his cousin). He was also named Time Magazine's Person of the Century in 1999, and, perhaps coolest of all, he's got his own chemical element; number 99, 'einsteinium.'

Here's to you, smartest non-virgin in history!
