Given a cartoon image and a caption. Caption: The window cleaner brings a pastry. Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
A surreal joke about a wise old man who lives on the side of a building --- the rock climber didn't expect to encounter him, but, without missing a beat, the old man says that the window cleaners (who also spend time on the side of the building) treat him well by bringing him pastries (implying that the rock climber should also have brought him a pastry).
