Today the new guy at work (who's been there six months, but he's still newer than me) made a subtle Hitchhiker's Guide to the Galaxy reference in conversation. (Not quite as obscure as this, but still obscure.) It's nice to be among my people.
Oh, you want to know what the reference was. It was about a guy's job being the kind of job where you'd sit behind a door labelled "Beware of the Leopard."
