Given a cartoon image and a caption. Caption: Somebody carve 911. Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
The person with the dinosaur attached to their leg is in immediate medical danger due to the bite --- in the modern world, such a dangerous occurrence would be responded to by calling 911 for emergency medical help, but here, there are no telephones, and communication happens instead via carving into walls (though, it's unclear exactly how carving 911 would lead to medical help arriving).
