Clever Couple

A couple in their seventies went to a sex therapist's office in Melbourne..

The doctor asked, 'What can I do for you?'
The old man said, 'Will you watch us have sex?'
The doctor looked puzzled, but agreed.

When the couple had finished, the doctor said, 'There's nothing wrong with the way you have sex,' and charged them $50.
This happened several weeks in a row. The couple would make an appointment, have sex with no problems, pay the doctor, and then leave.
Finally the doctor asked, 'Just exactly what are you trying to find out?'

The old 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 $90. The Hilton charges $170. We do it here for $50 and I get $43 back from Medicare.

Is Australia great or what?'
