I am such a geek. I totally squealed out loud when I saw this wee bit o' tasty at Starbucks today:
Even better: one of the baristas totally squealed with me. Our co-workers (I'd walked up to the coffee shop with another teacher) were...nonplussed, to say the least.
(It's Einstein's birthday today too, it's not just a geeky math thing. For the record.)
