A man with a long term problem of a dripping willie gets fed up of the embarrassment and ruined clothes and goes to the doctor for advice
He is told, "there's no regular cure, but I have a colleague who believes he's come up with the answer"
The man goes to see him and the colleague explains, "I'm pretty sure it works but the operation is pretty painful; I have to take a hair from your nose and insert it as far up your penis as I can manage"
He agrees and undergoes the very uncomfortable process and is told, "now go off and try it"
He does so, has a pee and waits; he is dismayed to see a large dewdrop appear
It hangs there; he waits and waits and waits, until finally his willie gives a huge "sniffff"
