A little paper bag was feeling unwell, so he took himself off to the doctors.

"Doctor, I don't feel too good," said the little paper bag.

"Hmm, you look OK to me," said the Doctor, "but I'll do a blood test and see what that shows, come back and see me in a couple of days."

The little paper bag felt no better when he got back for the results.

"What's wrong with me?" asked the little paper bag.

"I'm afraid you are HIV positive!" said the doctor.

"No, I can't be - I'm just a little paper bag!" said the little paper bag.

"Have you been having unprotected sex?" asked the doctor.

"No, I can't do things like that, I'm just a poor little paper bag!"

"Well have you been sharing needles with other intravenous drug users?" asked the doctor.

"No," says the little bag sheepishly, "I don't do things like that - I'm just a little paper bag!"

"Perhaps you've been abroad recently and required a jab or a blood transfusion?" queried the doctor.

"Oh no, I don't have a passport - I'm just a little paper bag!"

"Well", said the doctor, "are you in a homosexual relationship?"

"Oh dear me no, I told you I wouldn't do things like that, I'm just a little paper bag!"

" Hmmm, well I'm stumped" said the doctor

Suddenly, the little paper bag gasps in horror as the realisation hits him. In a little frail voice he stammers.. 

"I've just remembered, I think my Mum was a carrier"
