A son decides that he must finally place his elderly father in
an nursing home.  Both the son and the father are depressed,
but the deed is finally done.

The first day there, the old man is sitting in his room, stewing
about the whole deal when a beautiful nurse comes in and proceeds 
to give him a blow job.

Later, he calls his son and says, "Son!  I know I said I'd hate
it here and I'd never forgive you, but I was wrong.  I love it
here!  I just got the best blow job of my life!  Wow, what 
a great place!"

The son is obviously relieved about this.

The next day, the father decides to go out of his room and take
a walk.  A few steps down the hall, he drops his cane. As he 
bends over to pick it up, a male orderly comes up behind him and 
takes him in the ass.

The father calls his son back.  "Son!  I was wrong.  I hate it 
here!  I just dropped my cane and got sodomized by someone"

The son tries to be helpful and says, "Oh, but Dad, you gotta
take the good with the bad.  Remember the beautiful nurse and 
the blow job?"

"Yeah," says the father, "but son, I only get a hard-on once a 
month.  I drop my goddamn cane two dozen times a day!"
