a very sick man

This is a very sick man who is led by his son
hospital. There, after the many and varied tests, the specialist
bad news tells him that he is dying of
cancer, and at the stage where things are, so to
saving treatment! On leaving, the father said to his
son:
- Listen, I enjoyed the life. It's not that bad,
huh? Come on, take me for a drink at the café. and
're off the usual boozer. The on-site meeting paternal
several of his friends, and he took the opportunity to tell them that it is
dying of AIDS ...
When the friends leave the son asks his father:
- But why did you tell them that you had AIDS? it is
you have cancer!
- I know, I just did not want them to make me
cuckold after my death.
