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?"
"NO" she replies
The gentlemen says, "Good, wouldn't want to catch it twice."
