KFC is giving away free mouth expanders. They've developed a unique tool which you can put in your mouth, to slowly stretch it wider enabling you to fit more (burger) inside. The Mighty Burger stands a glorious 62mm tall. The average human mouth only opens to 49mm. So we needed to gain - on average - an extra 13mm.
