Blackboard Blues

BLACKBOARD BLUES I woke up this morning and I had the blues And the blacks and the Reds and greens whence to choose In days gone by when boards were black And teachers weren't wary but on the attack Chalk was as white as snow filled skies You could tell a school master by the dust on his flies But now boards are white and we've ink on our fingers And the odour of liquor that inculpates and lingers Use markers that erase and be sure they're never Permanent and fix your mistakes there forever You should also remember these pens may be dated And leave you with writing that's etiolated With a piece of chalk you would know where you stood Be it long short or tall it could make its mark good Then if your mind blanked, went as clean as a whistle You could turn round, take aim, and launch it as a missile
