Describe how the doctor examined the writer and bring out its humour.

Jerome frequently uses Observational humor which sometimes overlaps with satire. In a flashback, J. recollects how he once went to the British Museum to research a treatment for his hay fever, and after reading about diseases, convinced himself that he was suffering from every illness known to man except for housemaid’s knee. J.’s doctor, clearly recognizing the man's paranoia, prescribed him beefsteak, beer, walking, and good sleep habits, and urged him not to “stuff up your head with things you don’t understand” (10). The dry rather self deprecating humour of it all plainly comes out.
