Today's Sitting Tennant is from Saturday's Einstein and Eddington, which I still haven't watched. Oh well. It's on my iPod – I"ll get round to it at some point. It involved two scientific geniuses, one of whom was probably gay, one of whom wasn't – parallels to Last of the Time Lords, I wonder?

Anyway, captions please. They can involve that haircut.

Notably, this is Mr Electric Dragon's first entry in the picture competition aspect of Sitting Tennant; even more notably is that Ms Rullsenberg, on six and a half points, didn't take the opportunity to submit another entry in the competition and take over the lead from the dormant Rosby, who's still on top seven points, so she remains in second place. Persephone isn't too far away on five and a half points, Toby has five, Poly and Scott both have three and a half points each, Jane has two and a half, Anna and Electric Dragon have one and a half each, while Marie has one.

The Witty And Amusing Captions league table hasn't seen much change but everyone is looking very verved up and witty, with a concerted effort by all the assembled commenters. Toby has now hit the 20 captions mark, so kudos to him. Marie stays in second on 13. But now Jane Henry has overtaken Persephone to take third place on 10 and a half captions to Persephone's 10. Rullsenberg now has eight and a half, Electric Dragon and Rev are still tied but are on four entries each this time, and Poly and Stu_N are stuck on one each. New entry Andrea has chimed in as well, so she joins them on one, too.

As always, keep your eyes peeled for any new pictures of David Tennant sitting down that you can find, and keep coming up with those captions – there'll be bonus points for topical captions and pictures if you can find them.
