Given a cartoon image and a caption. Caption: You can tell the judge why you were doing CX in a XXV. Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
The police officer is from roman times (horses, outfit) --- such a police officer would use roman numerals for numbers, so instead of arresting the speeding person for doing "110mph in a 25mph zone", they scold them for "doing CX in a XXV".
