Given a cartoon image and a caption. Caption: Apparently, even the Fantastic Four can feel the pinch of the recession. Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
The diners are implying that the Fantastic Four had to get a job running a restaurant to make money during an economic downturn: the long arm is that of Reed Richards, a superhero with the ability to stretch his body. The contrast between superheros saving people vs. working in a kitchen during hard times is what makes this funny.
