Well, son, we Irish celebrate when things are good, and we celebrate
when things don't go well. In this case, things aren't so well. I have
cancer. Lets head to the pub and have a few pints."

After 3 or 4 pints, or more, the two were feeling a little less somber.
There were some laughs and some more beers. They were eventually
approached by some of O'Malley's old friends, who were curious as to what the two
were celebrating.

O'Malley told them that the Irish celebrate the good as well as the
bad. He went on to tell his friends that they were drinking to his impending
end. He told his friends, "I have been diagnosed with AIDS."
The friends gave O'Malley their condolences, and they had a couple of
more beers. After the friends left, O'Malley's son leaned over and whispered
his confusion.

"Dad, I thought you told me that you were dying of cancer, and you just
told your friends that you were dying of AIDS!"

O'Malley said, "I don't want any of them sleeping with your Mother
after I am gone."
