[Talian]

A man and woman were at a bar having a drink. One thing led to another, and they began chatting, finding out that they were both doctors.
After an hour or so, and after getting along reasonably well, the man asked the woman, 'Listen, we are both professionals - why don't we have sex tonight, no strings attached!'
The woman doctor agreed, and returned with the male doctor back to his place. He went to the bedroom, and she to the bathroom - to prepare.
She undressed and began scrubbing her hands like she was going into the operating theatre. After ten minutes of scrubbing, she eventually went into the bedroom, and the two doctors had sex.

Afterwards, the man said, 'I'm guessing that you're a surgeon, right?'
'Yes,' replied the woman. 'How did you know?
'I could tell by how clean your hands were when you came back from the bathroom,' he replied.
'That makes sense,' she said. 'I'm guessing you're an anesthesiologist, right?'
Surprised, the man said, 'Yes I am! How did you know?'
'Because I couldn't feel a thing,' she replied.
