Man is taken to hospital and diagnosed as having Aids. Kept in a seperate room, his mother visits him every day, but is kept in the corridor. Doctors not sure how contagious it is. She says to the doctor "Are you giving him anything at all"? Doctor replies, "Oh, yes, pancakes and kippers three times a day." "Oh", says the mother, "Will that cure him"? "Probably not", replies the doctor, "But that's all we can slide under the door".
