Black Board Blues 2

BLACKBOARD BLUES 2 When I woke up this morning I sure had the blues And the blacks and the Reds and greens whence to choose In the days long gone by when the boards were all black And teachers weren't wary but on the attack Then the chalk was as white as the snow filled the skies You could tell a school man by the dust on his flies Ah! But now boards are white and we've ink on our hands And the odour of liquor inculpates and brands Just use markers that clean and be sure they don’t stay Permanent so they fix your mistakes there for aye You should also remember these pens may have dates They could leave you with writing that etiolates With a good piece of chalk you would know where you stood Be it long short or tall it could make its mark good And then if your mind blanked, went as clean as a whistle You could turn round take aim, and launch it as a missile
