Slide under the door

"A man goes into the doctor's office feeling really bad.
After a thorough examination the doctor calls him into his office and says
'I have some bad news. You have HAGS.'
'What is HAGS' the man asks.
'It's herpes, AIDS, gonorrhea, and syphilis' says the doctor.
'Oh my God' says the man. 'What are you going to do?'
'We are going to put you in an isolated room and feed you pancakes and pizza.'
'Is that going to help me' says the man.
'No' says the doctor. 'But it's the only food we can think of that
we can slide under the door.'"
