Given a cartoon image and a caption. Caption: You knew your wife might remarry. Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
The angel is scolding the deceased man for trying to stop his mortal wife from re-marrying another person by throwing the lightning bolt at her back on earth. When people die, it's common for their spouses to get married, but this man, despite being dead, isn't comfortable with that. It's funny in part because one would think that ascending to heaven would alleviate petty, earthly concerns like jealousy, but, it didn't for this man.
