i went to a favorite pub in sydney a few weeks ago with some non-astronomer friends, who started making fun of me immediately when i arrived, because i was wearing my star wars t-shirt. i defended myself, in vain.
when it was my round for drinks, i went up to the bar with one of these friends so we could decide what kind of beer we wanted. while in the queue, i thought maybe i recognized the silhouette of someone there. sure enough, despite the hundreds of bars in sydney, there were a few astronomers at the pub who happened to be attending a conference in sydney that week.
i walked up, tapped an astronomer friend on the shoulder, and when he turned around i happily pointed out that he was also wearing a star wars t-shirt :)
i'm not sure if that actually helped my case, but i felt somehow vindicated!
