There has been a mix up with your notes.
You're booked in for wart removal but the Doctor has you down for a vasectomy.
You apologise for their mistake and make it very clear that you will not be having a vasectomy!
The hot headed Doctor is not happy about this and insists on going ahead anyway.
You're numb from he waste down. unable to move, all you can do it shout and plead.
This becomes very distracting and the Doctor becomes more and more unhinged..
