A brief history of my day.

"Aha! Here's where you've been going wrong, Professor Hawking - it should be pi squared!"

OK, so I didn't really help find the answer to the Great Question of Life, the Universe and Everything (or even what the question is) but I did discover one thing. While all the other women at Madame Tussaud's were fawning over Johnny Depp, Tom Cruise and some guy I'd never heard of called 'Robert Pattinson', I seemed to be the only one making a bee-line for the geek section.
