The quote humorously criticizes a character's lack of charm and social skills, comparing him unfavorably to a rectal probe, which is typically associated with discomfort. This establishes his unlikability, suggesting that he's the kind of person that others avoid, highlighting his loneliness and social isolation. The imagery of dogs enjoying their lives contrasts sharply with the character's dreary existence, suggesting that even animals have a better outlook on life.

This comparison implies that while the character struggles to connect with others and find joy, dogs find fulfillment in simple pleasures. The author, Christopher Fowler, uses this imagery to emphasize the character's unhappiness and to provide a comedic yet poignant reflection on the human condition, showing how some individuals may feel trapped in their lives, lacking the joys that even pets experience.
