Hamster examining joke

A man brings his hamster to the vet's office and lays the hamster on the examining room table. The vet looks at the hamster and says: "I'm sorry sir, your hamster is dead."

Not at all happy with the vet's diagnosis, the man demands, "I want a second opinion!"

The vet whistles and in comes a Labrador Retriever. The lab sniffs the hamster for a minute, looks up, and shakes its head. "The lab says your hamster is dead." replies the vet.

"I want a third opinion!" The man demands. So the vet opens the back door and in bounds a cat, who jumps on the table. The cat looks the hamster up and down for a few minutes before looking up and shaking its head. The vet responds: "Your hamster is definitely dead, sir."
 
"All right what do I owe you?" The man asks, finally satisfied with the diagnosis.

"That will be $650, please." The vet replies.

"WHAT?? $650 just to tell me my hamster's dead?"

"Well sir, it would have only cost you 50 dollars for my diagnosis. However the other $600 was because you insisted on having the cat scan and the lab test."
