The Cat Scan

One day, Ricky's dog got seriously ill. So, he took it to a veterinary doctor. The doctor examined the dog and declared it to be dead.

Ricky felt very sad and asked the doctor, "Doctor, are you sure that my dog is dead? Kindly perform some tests and confirm it to me." The doctor agreed and asked his assistant to bring a cat. The cat sniffed the dog and went to the other room without any reaction. Thus, it was confirmed that the dog was dead.

When Ricky asked for the bill, the doctor demanded two hundred dollars. When Ricky asked why the bill was so high, the doctor replied, "Cat scan is really very costly."
