An Indian couple both age 37, went to a sex therapist's office.

The doctor asked, "what can I do for you?"

The man said, "Will you watch us have sexual intercourse?"

The doctor looked puzzled, but agreed. When the couple finished having
the intercourse, the doctor said, "There's nothing wrong with the way you
have intercourse", and charged them R70.

This happened several weeks in a row. The couple would
make an appointment, have intercourse with no problems, pay the doctor, then
leave.

Finally the doctor asked, "Just exactly what are you trying to find out?"

The man said, "We're not trying to find out anything.  She's married and we
can't go to her house. I'm married and we can't go to my house. The Holiday
Inn charges R225. The Hilton charges R879. We do it here for R70, and I get
R65 back from Discovery!"
