A couple of weeks ago, a friend and I were at the local pub, when this guy in urban camo fatigues walks in. All heads turn and watch as he sits down with a dozen or so nondescript types. Nothing particularly unusual, except that there's this red patch on his shoulder that looks vaguely familiar ? the symbol looks a bit like a black swastika on a red background.

So we're thinking, Hey. Has our neighbourhood pub been invaded by neo-nazi punks? We both take a closer look at the arm patch. We'd seen it before... but where? We don't know if he's just some loser, or if he's a neo-nazi punk deserving a good frowning from across the room (there were a dozen of them).

This morning it hit me. It's the symbol of the invading army of lizards in the 1980s TV series "V".

So does that mean that he's just an extreme sci-fi geek?
