It’s Possible to Pull Out a Grenade Pin With Your Teeth
Contrary to popular movie beliefs, people cannot pull out a grenade pin with their teeth. If you’re ever stuck in that situation, don’t waste your time trying something so impossible and non-realistic–call for backup instead.
The pins on grenades are deliberately tough to pull so that the grenade won’t accidentally go off. It generally takes two hands and some effort to get the pin out. So, if you’re thinking about trying to replicate a movie stunt by pulling the pin out with your teeth, be sure to schedule a dental appointment first—you’ll lose a few teeth in the process.
