And just for fun, read the lyrics to Global View. Special offer: Find and document the inconsistency in the numbers given in this song, and win a free Milky Way bar! (Fine print: Documentation must be submitted in writing. The inconsistency is significant, not a mere round-off error in the 10% range. Although you may check the numbers in the song against other sources, your documentation should demonstrate an internal inconsistency, within the song itself.)
