"John, John, that's what I'm a callin' Hurry up and haul that coal" ("I hauled that yesterday") "John, John, I'm not only stallin' ("Go away, ah, let me be") This old lady's up to somethin' sure as you're born" As you listen to granny cackle, she found your fishin' tackle A whistle for all your plans now for the good they'll do Look at granny, she's got the flivver, she's headin' for the river Well, isn't that like a man's mother-in-law for you
