What causes Arthritis?

[Gh0st Face Killah]

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.'
