Talk about jokes. My guy suggested that exam a couple of years ago when I had blood in the toilet. When I am leaning over his desk, and he was putting the lube on his glove, he wanted to break the ice. He said, during the test, you will feel my hand on one shoulder. If you feel my hands on both shoulders during the test, you can call the cops.
Just as i started to crack up, he snuck the finger in. The diversion worked.
