An unscrupulous businessman was feeling very ill and
went to the doctor. The doctor examined him and backed
away, saying, “I'm sorry to tell you this, but you have
an advanced case of highly infectious rabies. You must
have had it for some time. It will almost certainly be
fatal.”

“Could you give me a pen and paper?” said the businessman.

“Do you want to write your will?”

“No, I want to make a list of all the people I want to bite.”
