A couple in their 70s went to a sex therapist's office in Melbourne....

The doc asked, "What can I do for you?"

The old man said "Will you watch us have sex?"

The dog looked puzzled, but agreed.

When the couple finished, the doc 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 doc and then leave.

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

Old guy replies, "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. Hilton $170. We do it here for $50 and get $43 back from Medicare. Isn't Australia great or what?"
