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："That's extremely tolerant of you, especially after what he just did."

"Not really," came the reply. "I'm just finding out where his mouth is, so I can kick him in the nuts."

一个盲人领着一只导盲犬站在十字路口处等着过马路。就在这个时候，导盲犬把腿一抬，开始往主人身上撒尿。

这个盲人十分平静地从口袋里拿出了一块饼干给狗吃。一个过路人刚好看到了这一切，很不解地说：“你的脾气真好，尤其是那只狗都做了这样的事情，你还给它饼干吃。”

“事实并非如此。”盲人回答说，“我只是想弄清楚它的嘴在哪里，这样一来，我就可以踢它的屁股了。”
