Couldn't they find a real astronomer?
Along with the usual ones about black holes and planets during Ask an Astronomer in the visitor centre today, there were a few daft questions from the audience. One guy asked "Couldn't they find a real astronomer today, is that why you're here?" Later on, from the same group, a guy asked something along the lines of "I'm an Aquarius, what in store for me in September?" Very silly. Whether they wanted it or not, they got a quick description of why astrology is a load of dingos kidneys :-).
