"Doctor, I don't feel so good." Said the little bag.
"Well," said the doctor "you look okay, but lets do some blood tests and see if we can find out what's wrong with you. Come back and see me in a week."
The little brown paper bag wasn't feeling any better when he went back to get the results. "What's wrong with me, doctor?" he asked.
"I'm afraid you're HIV positive." said the doctor.
"NO!" Cried the little bag, "I can't be! I'm only a little paper bag!"
"Have you been having unprotected sex?" asked the doctor.
"No, I told you, I can't do things like that! I'm only a little paper bag!"
"Well then, are you having a homosexual relationship?"
"No, I've already said, I can't do things like that. I'm only a little paper bag for heavens sake!"
"How about an intravenous drug user?"
"No, I am a pure innocent little paper bag"
"In that case," said the doctor, "there's only one possible explanation..."
This is quite good, wait for it...
"Your mother must have been a carrier."
