"What weighs more -- a bomb or a head?"   A bomb can be said to be heavy   But a head is much more deadly   A grenade in the hand could have   prevented Custer's last stand   But making a bomb fit for mystics   One must first have a head filled with physics   An old cannonball can still prevent   Tomorrow's roll-call   But if we want them all dead   We must fuse all our heads,   So we'll run out of people tomorrow      People are an unwholesome lot   They should all be taken out and shot   But if we make them all dead   Who will bake all our bread?   And if there's no food to carve   I guess we'll just starve   And if that upsets your conviviality   (remember) Hunger knows no morality   So when we rent that one final coffin   I guess we'll all just diet more often
