Flatulance!
Man goes to the doctor's for the result of his blood test,
Doc says 'bad news I'm afraid, you have green monkey's disease,
cholera, diphtheria, lassa fever, ebola, gonorrhea, herpes and AIDS.'
'Oh my God Doc' says the man 'what am I going to do?', 'well', says the Doc,
'We're going to rush you off to the isolation ward at the
hospital and put you on a diet of pancakes and pizza'.
'Will that make me better' says the man hopefully,
'No', says the doctor 'That is the only thing that will fit under the door'.
