All my recitals came at school. I did the balcony scene from Romeo and Juliet, the entirety of The Walrus and the Carpenter (240 lines! sheesh!), and of course the preamble to the U.S. constitution (which I had memorized from the Schoolhouse Rock thing on Saturday morning TV, so it wasn't hard at all!).
But good point, Peter T., about having stuff in one's head. I'm told there are monks who memorize the whole of the Bible. That may be carrying it a bit too far!
