Given a cartoon image and a caption. Caption: O.K., they're yours, but I still don't know where you got that fourth ace. Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
The priest and the devil had been playing cards where the stakes were the people's souls. The devil cheated at this card game. It's funny in part because, even though the priest recognizes that the devil pulled an extra ace from nowhere, he doesn't seem to register or expect that the devil cheated. His response to turning over these souls to satan is humorous nonchalant.
