You may recall the phrase "hot dogs or legs" - a social media trend where photos of tanned, glossy legs were compared to hot dogs, often showing such similarities it was hard to tell the difference.
Today, Twitter is awash with a new food versus body part craze. This time, it involves the impossibly chubby arms of babies being likened to bread.
Hundreds of parents in Japan have taken to social media to share shots of their babies' arms alongside sticks of pull-apart bread loaves.
The flurry of images was sparked by user Koni (@sn15papa), who posted a photo last week with the caption "Which is bread and which is the arm? I can't tell."
