'Doctor, I've left my wife.'
'Well, bring her in. I 'm happy to see you both together.'
'No. We've parted company'
'Sometimes husband and wife shouldn't be in the same business.'
'I've not been clear enough, Doctor. You see, we just didn't get on.'
'I'm not surprised. You have to be very clever to ride a horse together.'
'We're getting a divorce'
'Whose the lucky man?'
