i went to the doctor and said: 'what can you give me for wind?'
he handed me a kite.

i went to the doctor, and said: 'doctor, i have terrible flatulence.  what can you do about it?'
he went out of the room and came back with a long stick with a metal hook on the end of it.
i squirmed in my chair.
'what the hell are you going to do with that?' i asked.
'open the window,' he said. 'it stinks in here.'

i quite like doctor jokes, probably because every doctor i have ever known has been a miserable bugger.
