not sick, but funny, i think
a gynaecologist has decided to give up his jub and become a vehicle mechanic. There are three parts to his exam: changing the oil, changing a tyre, and refitting all the internal parts of the car.
When he gets his results back he finds that for the first part he has scored 100%
for the second part he has also scored 100%
when he reads the result for the third part he is somewhat puzzled, having scored 110%

he decided to ask the examiner why he achieved such good results. The examiner explains
"Well, you did the first to parts with such precision and perfection that it was the only mark that we could give you. And for the third part, not only was it done perfectly, you managed to do the entire thing through the exhaust pipe!"
