When my brother and I were little, perhaps first grade, our favorite song was "Rainy Day Women #12 & 35". We were convinced that the line "everybody must get stoned" (and the entire chorus surrounding it) was about medieval times, and used to run around the house shouting those few lines ALL THE TIME. Our parents used to have us stand on top of the piano and sing it frequently when we had guests over, and we never understood why everyone found us so funny!
