A blind man was waiting to cross the road when his guide dog cocked its leg，then urinated on its owner。 Calmly， the blind man reached into his pocket and took out a biscuit for the dog。 A passerby who‘d seen everything remarked：“This extremel tolerant of you，especially after what he just did。”

“Not really，”came the reply。“I am just finding out where his mouth is，so I can kick him in the nuts。”

一個盲人和他的導盲犬站在十字路口上，正等著過馬路。這時那個導盲犬把腿抬了起來，開始小便。毫無疑問，盲人的褲子溼了。但是這個盲人卻平靜的從口袋裡拿出了一塊餅乾給狗吃，一個看到一切的過路人，對此很不解的問道：“你的脾氣真好，那條狗都做了這樣的事情，你還拿餅乾給他吃。”

“不是這樣的。”盲人回答道：“我只是想知道它的嘴在哪裡，這樣我就可以踢他的屁股啦。”
