The doctor: Now we shall check up, the smart guy, be not stirred.. (shows a sheet of a paper on which the triangle is drawn).. What is it, your way?
The patient: (is confused giggling): Oh, the doctor, well to me it is right even somehow inconveniently...
The doctor: (showing other drawing, with a square): So, well, and it that?
The patient (still): It\"s nothing, the doctor, well as I can, well unless it is possible....
The doctor: Clearly... (starts to fill in a case history)
The patient: the Doctor, and you not the sex maniac?
The doctor (in marginal surprise): Why???
The patient (artfully): And whence at you such a pictures?
