Identify some of the improbable images the author has used to effect greater humour.

The author has used great humour to describe the trouble he goes through to get his watch repaired seven times from seven different people after it had run properly for eighteen months and had eventually run down. The author uses exaggeration to add humour to the story in certain places to keep the readers entertained. The author uses hyperbole to add humour when he says that he feels like he is going back in time because it is physically and practically impossible to go back in time. It is funny when he describes his watch as having a fever and is enjoying the season of snow before it had even arrived. It is hilarious that the author compares his situation to that of a bygone and old mummy lying in a museum.
Thus, the improbable images put forth in the story by the author add to the humorous element of the story.
