It common knowledge that girls like to talk a lot, but this girl literally can’t shut her mouth! The girl in the video below reported to the emergency room unable to close her mouth after a history class literally left her speechless. As it turned out, the girl was at college attending a class. I’m pretty sure the lesson wasn’t particularly interesting as the young woman opened wide for yawn right in the middle of it. Believed or not, this caused her jaw to dislocate leaving her unable to close her mouth. I never knew something like this could happen out of boredom, now I’m afraid to listen to my grandpa talk about the good ol’ days.
