He passes the certificate to Mayor Winters. "No doubt about it," he adds, just to make sure that he gets his point across.

I suppose the most surprising part of this whole thing is the fact that the old hag had a heart at all." "If I had a penny for every time someone's made that joke today," Dr. Wellington points out, "I'd be able to retire by teatime."

Did the old dear hurry him along with some switched pills?" "Who knows?" Dr. Wellington replies. "Such matters are beyond my area of expertise, although I've heard all the same rumors as everyone else.
