English Original
A blind man stood at a street corner with his guide dog, waiting to cross. Suddenly, the dog lifted its leg and urinated on the man's fine herringbone tweed trousers. The man promptly took a dog biscuit from his pocket and offered it to the dog.
A businessman observed this from across the street. "Excuse me, sir," he called out, "did you know your dog just urinated all over your pants?"
"Yes," replied the blind man. "It's a dreadful habit I'm trying to break him of."
"Well, it's none of my business," said the onlooker, "but you won't teach him much by rewarding him with a biscuit!"
The blind man chuckled and said, "I'm not rewarding him. I'm just trying to find his head so I can kick his behind!"
中文翻译
一位盲人带着他的导盲犬站在街角，等待过马路。突然，狗抬起腿，在他精致的鱼骨纹粗花呢裤子上撒了尿。盲人立刻从口袋里掏出一块狗饼干，递给了狗。
一位商人在街对面看到了这一幕。"打扰一下，先生，"他喊道，"您知道您的狗刚刚在您的裤子上撒尿了吗？"
"知道，"盲人回答。"这是个坏习惯，我正试图让他改掉。"
"好吧，这不关我的事，"旁观者说，"但用饼干奖励他，你可教不会他什么！"
盲人轻声笑了笑，说道："我不是在奖励他。我只是在找他的头，好踢他的屁股！"
