Joke

A woman takes her dog to the vet and tells him that she thinks it's dead. He puts the dog on the table and turns to take a cat out of cage nearby. He places the cat by the head of the dog and the cat then proceeds to walk along the dog. The dog doesn't move.

"Your dog is definitely dead, madam. And that will be $120.", concludes the vet.

"Good gracious.", replies the woman, "how could it be so much?"

"Well, that's $20 for my consultation and $100 for the cat scan."
