Captain Renfro Louise Kept the black dog* off his shoulder, During the gloom of cold-shortened days With a few pegs of afternoon grog At the Moaning Raven Tavern... Wet and slick and dully lit Like the midnight barracks Of sotted marines... The last place one should be, When fighting the dark yips. But Cap'n Ren had faith That the next peg, always the next one, Would put a stake Through the heart of the black dog... A pursuit of notable persistence, And predictable failure, But one he swore to keep at, Until nirvana's light shown At the end of the tunnel. *Samuel Johnson, and later, Winston Churchill were credited with naming their depressions, "the black dog."
