Tell you a story. A couple of years ago, Cliff and I were at Heroes Con in Charlotte. We were wandering the dealers room, not finding much to buy, but having a lot of fun. We passed a table that was being manned (Klingoned?) by two fans in absolutely perfect Klingon costumes. Full make-up with brow ridge and the whole nine yards. I happened to make eye contact with one of them and he snapped me the Klingon salute, which is basically the Roman salute. Fist to chest, then arm extended. Without really thinking about it I returned the salute.
When we were past the table Cliff said, "You just saluted a Klingon."
"When in Rome," I said.
