How I did not get into 
the Daily Show for my 50th birthday, even with a VIP reservation...

That's me!  Craning my neck to show you that I am there on time.  Awaiting my VIP ticket.  My wife's surprise for my big 5-0.  But it seems I was not a VIP after all.  Only at the Annual Math Meeting.  Even there...not so much.

Improv with ASSSSCAT 3000

The brilliant improvisational comedians at the Upright Citizens Brigade asked me to be a guest monologist. Who would have thought they could get such laughs from Fermat's Last Theorem?

Carole and I celebrate the heroes who unified Italy and made it what it is today -- a boot shape with lots of pasta.

On our way to warm up at The Trout, a cozy pub near Oxford, on a typically raw day. This part of the path was flooded, so my friend Nick suggested we save our boots and brave the waters barefoot. Brrr!

Lecturing in Auditorium A of The Niels Bohr Institute -- he designed these sliding boards himself!  He should have invented a multi-sponge car-wash-style cleaner, too.
