I went to the Babelcon in Baton Rouge with my friend Anne. She knows Star Trek and Star Wars but the other shows aren't her thing. One of the guys about 22 years old was dressed up as Dr. Who 4.5 and had a name tag that just said "the doctor". Anne asked "Who are you". and of course I said "you're right". She then said "What" and I said "he's on second". She then said" I don't know what you are talking about". The kid said "Third base".
If that young person knows Abbott and Costello, then there is hope for the world.
