Given a cartoon image and a caption. Caption: It deployed when her carriage rear-ended an ox cart. Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
The woman's oversized ruff collar is juxtaposed against the modern invention of an air bag. Air bags deploy during car crashes --- and here, the collar inflated during a collision between a carriage she was riding in and an ox cart as a safety mechanism. It's funny in part because, while it explains the oversized collar, collars are cosmetic rather than functional.
