Ode to Guinness
Some Guinness was spilt on the bar-room floor Just around closing one night, And a wee little mousie crept out of his hole And into the pale moonlight. He lapped up all of that dark frothy brew And back on his haunches he sat, And all the night long you could hear that mouse roar, "Bring on that god-damned cat!"
