Given a cartoon image and a caption. Caption: Heal! Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
A play on the words "heel" and "heal". A doctor might hope their patient would heal from a disease. A dog might be taught "heel" as a command which means for your dog to come and stand next to you. Here, the doctor's command has both meanings, because the dog is the patient.
