"I'm sticking to the Murphys, I'll fight 'em till I die; I can't help spitting cotton Because I am so dry. You'll bust your lips with laughter; Stick to the pledge I must, But the more I drink cold water The more I'm belching dust."
The Murphy movement was a temperance program of the 1870s or so. Men signed a pledge to avoid alcohol (and to try to convince others to do the same), and were rewarded with a blue ribbon. - RBW
