Not sure if this one has been mentioned (this is a long thread!), but....you know you're a fan when you get really, truly outraged when someone insults the Beatles. A few days ago someone in a different, non-music forum happened to mentioned that the Beatles sounded like "nails on a chalkboard." WTF? I was so mad. (This person has obviously never heard "Because.")
I mentioned this briefly in the "Irks" thread in a separate area of this forum, and I have to say, I am still steaming! I can understand -- sort of (not really) -- someone not caring for Beatles music, but comparing them to "nails on a chalkboard" really, REALLY ticks me off.
