Given a cartoon image and a caption. Caption: Wake up, Harold! You're having another of your delusions of grandeur. Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
This scene takes place in a man's mind --- in his delusion, he is a judge in a courtroom, perhaps passing judgement on one of his rivals. This is a delusion of grandeur because judges have a lot of power. But, his daydream is interrupted by his wife entering the room, which manifests as her walking out of a door in the judges stand (in real life, she probably just walked into the room he was in).
