In case you Stateside people dont know him, Stephen Fry is a British actor, comedian and novelist and very well known in the UK.

I was walking to my office in Soho (London, not NYC) and turn the corner only to bump straight into a large sized man chatting jovially into a mobile phone. I am not short, but my head hit him just above his chest. Anyway, I look up, straight into the face of someone I grew up watching on the Blackadder series. Not a good way to meet someone who's work I respect very much. Especially when he has to stop the conversation with the Important Person on the Other Side to say "Ooops, terribly sorry" in a very proper British lilt. In a moment of clarity, I said "No problem, Stephen.." like he was a friend of mine or I was just used to half tackling celebrities in the street. I hurriedly sought solace in my office before the cops showed up.
