1A pig is a jolly companion, 2Boar, sow, barrow, or gilt -- 3A pig is a pal, who'll boost your morale, 4Though mountains may topple and tilt. 5When they've blackballed, bamboozled, and burned you, 6When they've turned on you, Tory and Whig, 7Though you may be thrown over by Tabby and Rover, 8You'll never go wrong with a pig, a pig, 9You'll never go wrong with a pig! 10 -- Thomas Pynchon, "Gravity's Rainbow" 11
