Blaisedell, the poet, had said to him, 'You love beer so much. I'll bet some day you'll go in and order a beer milk shake.' It was a simple piece of foolery but it had bothered Doc ever since. He wondered what a beer milk shake would taste like. The idea gagged him but he couldn't let it alone. It cropped up every time he had a glass of beer. Would it curdle the milk? Would you add sugar? It was like a shrimp ice cream. Once the thing got into your head you couldn't forget it...If a man ordered a beer milk shake, he thought, he'd better do it in a town where he wasn't known. But then, a man with a beard, ordering a beer milk shake in a town where he wasn't known--they might call the police.
