A few of mine; "Take your teeth out tell me what's wrong" - Chiquitata (Abba), "Last night i dreamed of lumbago" - Madonna (La Isla Bonita) and for years i sang, "Lay lady lay, lay across my big brown spade" until an incredulous friend of mine (a proper Dylan fan) pointed out the error of my ways.
I always thought that the Elvis song said 'and my reason's aim' took me years to realise it said 'and Marie's the name' Always wondered why it didn't make sense!
