So on my way back to the office from lunch today, I see someone with a license plate:
I decide that if this guy parks anywhere near my office building, I am going to ask him if the plate has anything to do with the Perl Black Book
So I walk up to the parked vehicle and the guy cautiously rolls down the window and I ask "Does your license plate have anything to do with the programming language" as though it were the most natural thing in the world to say.
After a long thoughtful pause the guy chuckles and says no - it is from Pirates of the Caribbean. As I start to walk away with my head hung down he says "but I am a web developer and had never thought of that connection until now - thanks".
It made me smile
