A man runs into the vet's office carrying his dog, screaming for
help. The vet rushes him back to an examination room and has him
put his dog down on the examination table. The vet examines the
still, limp body and after a few moments, tells the man that his
dog, regrettably, is dead. The man, clearly agitated and not
willing to accept this, demands a second opinion.
The vet goes into the back room and comes out with a cat and puts
the cat down next to the dog's body. The cat sniffs the body, walks
from head to tail, poking and sniffing the dog's body and finally
looks at the vet and meows.
The vet looks at the man and says, "I'm sorry, but the cat thinks
that your dog is dead, too."
The man, finally resigned to the diagnosis, thanks the vet and asks
how much he owes. The vet answers, "$350."
"$350 to tell me my dog is dead?!" exclaims the man.
"Well," the vet replies, "I would only have charged you $50 for my
initial diagnosis. The additional $300 was for the cat scan."
