What causes Arthritis-zt

A drunk man who smelled like beer sat down on a subway next
to a priest.The man's tie was stained, his face was plastered with
red lipstick, and a half-empty bottle of gin was sticking out of his
torn coat pocket. He opened his newspaper and began reading.

After a few minutes the man turned to the priest and asked,
'Say Father, what causes arthritis?'

The priest replies, 'My Son, it's caused by loose living, being with
cheap, wicked women, too much alcohol, contempt for your fellow
man, sleeping around with prostitutes and lack of a bath.'

The drunk muttered in response, 'Well, I'll be damned,' then
returned to his paper.

The priest, thinking about what he had said, nudged the man and
apologized. 'I'm very sorry. I didn't mean to come on so strong.
How long have you had arthritis?'

The drunk answered, 'I don't have it, Father. I was just reading here
that the Pope does.'
