An Englishman went to his doctor complaining about a sexual problem, "Doc, I think my dick is just too damn small." The physician asked him which drink he preferred.

"Well, American beer," he replied quite bemused.

"Aaaahhh. There's your problem. It shrinks things, those silly American beers; you should try drinking Guinness. That makes things grow."

Two months later the chap returned to the doctor with a big smile on his face. He shook the doctor's hand and thanked him. "I take it you now drink Guinness?" asked the doctor.

"Oh no, Doc," replied the man, "but I've got the wife on American beer!"
