Good afternoon, gentlemen. I am a HAL 9000 computer. I became operational at the H.A.L. plant in Urbana, Illinois on the 12th of January 1992. My instructor was Mr. Langley, and he taught me to sing a song. If you'd like to hear it I can sing it for you.

comment How can the Earth keep spinning with a liquid core?
@BrandonEnright The leaves do not cause any measurable change in Earth rotation; other effects have much greater impact, e.g. tropical storms, mantle deformations, ice caps.
