A man comes from England to find out what the good old night life
     is like in Toronto. As he was walking down the street he meets this
     gorgeous whore who asks him if he would like a good time.   He says
     "Sure as long as it does not leave me broke" After a half-hour the
     man suddenly stops, asks "Do you have aids?" to which her reply was
     "no," and the gentlemen says "Good, wouldn't want to catch it
     twice."
