Guy goes to a doctor and says he has a problem
with sex. "I think my privates are too small." He says.
The doctor asks him which drink he prefers. "Well,
Lager," he replies, quite bemused.

"Aaaahhh. There's your problem. It shrinks things,
those Lagers. You should try drinking Guinness.
That makes things grow."

Two months later the chap returns to the doctor
with a big smile on his face. He shakes the doctor
by the hand and thanks him.

"I take it you now drink Guinness?" asked the doc.
"No", replies the man "but I've got the wife on Lager!"
