A couple, both 67, 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.  The doctor examined them and then
directed them to disrobe and go at it.  When the couple finished, the
doctor
reexamined them and, upon completion, advised the couple, "There's nothing
wrong
with the way you have intercourse."  He then charged them $32.

This happened several weeks in a row.  The couple would make an
appointment,
have intercourse with no apparent problems other than the lack of vigor
which is
to be expected in 67 year olds, get dressed, pay the doctor, and then
leave.
Finally after almost two months of this routine, the doctor asked, "Just
exactly
what are you trying to find out?"

The old man said, "Oh, we're not trying to find out anything. She's
married
and
we can't go to her house. I'm married, so we can't go to my house.  The
Holiday
Inn charges $60.  The Hilton charges $78.  We do it here for $32 and I get
$28
