One morning, Kevin wakes up to find his dog dead, lying next to his bed. He can't quite believe it, so decides to take him to the vet. The Vet takes one look at the dog and says, "Kevin, I'm truly sorry, but your dog is dead."

"No. He can't be dead. I demand a second opinion!" replies Kevin.

The doctor nods and agrees. He goes into the back room and brings out a cat. The cat jumps all over the dog, bites it, looks at the vet and says, "Meow."

The vet again says, "I'm sorry but your dog is truly dead."

Kevin says, "No!, I don't believe it, I want another opinion."

The vet nods and brings out a Labrador Retriever, which then begins to jump all over the dead dog, tugging at it before barking, "Woof roof woof!"

The vet says, "Sir, your dog is dead. That will be 400 dollars."

"$400 to tell me my dog is dead?" asks Kevin.

"Well," the vet replies, "I charge 50 dollars, the cat scan is 200 and the lab test is 150 dollars..."
