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, regrettable, 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 is still unwilling to accept that his dog
is dead.

The vet brings in a black labrador. The lab sniffs
the body, walks from head to tail, and finally
looks at the vet and barks.

The vet looks at the man and says, "I'm sorry,
but the lab thinks your dog is dead too."

The man, finally resigned to the diagnosis, thanks
the vet and asks how much he owes.

The vet answers, "$650."
"$650 to tell me my dog is dead?" exclaimed the
man.

"Well," the vet replies, "I would only have
charged you $50 for my initial diagnosis. The
additional $600 was for the cat scan and lab
tests."
