Given a cartoon image and a caption. Caption: Is that a new outfit? Question: Generating an explanation of why this image/caption combination is funny. Answer: 
assistant
This is an oddly nonchalant thing to say if one's partner was dressed in a hazmat suit. Usually: this is the sort of comment one would make if someone had a new shirt or a new pair of shoes, not a hazmat suit. Given that the woman is probably wearing the suit for a good reason, it's partly funny because the man's nonchalance/ignorance might be putting him in literal danger.
