Listen to me speak in 'The Black Speech'
by clicking this link. The producer did a great job, I think, in blending all of the material together, and the piece is pretty neat.
Back in fifth grade, my best friend Chipper and I wrote an adapted play of "The Council of Elrond" (yes, the one chapter in LotR where there's no physical action). I think our version is much better than Peter Jackson's, by the way. But in doing this I ended up memorizing the lines written on the One Ring: ash nazg durbatuluk, etc. This has come in handy many more times than you might expect.
