English Original
A man came home one day to find his dog lying on its back, legs in the air. Unsure if it was dead, he took it to the vet.
The vet said there was a sure-fire way to check. He left the room and returned with a cat, which he rubbed in the dog's face. After a moment, he concluded the dog was indeed dead.
The upset owner asked for the bill. "$550," said the vet. Stunned, the man asked for an explanation.
"Fifty for the visit," the vet replied, "and five hundred for the cat-scan."

一天，一个男人回到家，发现他的狗四脚朝天躺着。他不确定狗是否死了，便带它去看兽医。
兽医说有个万无一失的方法可以检查。他离开房间，带回一只猫，在狗的脸上蹭了蹭。过了一会儿，他断定狗确实死了。
心烦意乱的主人询问费用。"550美元，"兽医说。男人惊呆了，要求解释。
"50美元是出诊费，"兽医回答，"500美元是猫扫描（CAT-scan，谐音CT扫描）费。"
