A man went to the doctor and said - "Doctor, whenever I fart there's no smell".
The doctor asked the man if he could do one there and then, which the man did, very loudly.
The doctor sniffed a few times, said - "Yes, I think I know what the problem is", went out of the surgery for a moment and came back with a very long stick with a hook on the end.
The man became very frightened and asked - "Doctor, what are you going to do with that thing?", to which the doctor replied - "I'm going to open the window - you've got something wrong with your nose!".
