@Setanta,
Mr Jones goes to his doctor and complains that the cream he prescribed had caused a large tit to grow on his head.
The doctor looks at the tube of cream and tells him that he's been rubbing breast enlarger on his head, as opposed to the prescribed hair restorer.
"I think you've mixed medicines with your wife, Mr Jones"
"No wonder she's been shaving her chest", Jones replies, "but what the hell do I do about
my situation? I can't just walk around with a ruddy great tit on my head!"
"Well, Mr Jones, you could always paint it blue and join the Police Force."
Evenin' all.
