Given a cartoon image and a caption. Caption: Remember that domino factory? Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
A joke about an unusual construction company which demolishes buildings that have humorous interactions with the wrecking ball. Here, the wrecking ball is similar to a bowling ball knocking over the pins, and the workers are discussing the previous jobs. Like bowling pins, dominos are also knocked down after being arranged, and the wrecking ball accordingly played the same role at the domino factory.
