Pin-Pulling Teeth



The tough guy takes out a grenade and pulls the pin with his teeth, then tosses it to kill a bunch of mooks. It's a common trope in action flicks and war films.

In reality, grenade pins are designed to be hard to pull so they won't be pulled accidentally. Attempting to pull them with your teeth will likely result in some painful dental damage.

Straightening the pin in advance to make it easier to pull is certainly possible but it greatly increases the risk of mass casualty I Just Shot Marvin in the Face - style accidents.

 * In The Wrath Of God, one of the "heroes" is mortally wounded but grapples his killer -- then brings up one hand holding a grenade. Grinning into the other man's horrified face (at about four inches), he says, "Life is just full of surprises!" before pulling the pin with his teeth and holding the grenade alongside their heads. Boom.

Literature
"Yeah yeah, I know you always see the hero pull the pin out with his teeth. Well you try it sometime, if you want to send your dentist's kids to Yale. Because the only thing you're gonna get if you try and pull a fucking grenade pin out with your teeth is broken teeth."

While people have pulled grenade pins with their teeth (see the Real Life section below), it is certainly not as easy as the movies make it appear.
 * Ace's nitro-nine grenades in Doctor Who are made from scavenged aerosol cans, so they have caps instead of pins. In a possible allusion to this trope, the Doctor pops the cap off one grenade with his teeth in Remembrance of the Daleks.

Real Life
""Although twice wounded, once when struck in the back, the second time when a mortar shell fragment passed through his left hand and rendered it practically useless, he refused to withdraw and continued to lead his squad after hasty dressings had been applied. His serious wounds forced him to fire his rifle with 1 hand, resting it on rubble or over his left forearm. To blast his way forward with hand grenades, he set aside his rifle to pull the pins with his teeth while grasping the missiles with his good hand.""
 * The pin usually doesn't trigger a grenade. It is a safety device that prevents the grenade from being triggered accidentally. Not all grenades use pins and most modern grenades have three safety devices, usually the thumb clip, the pin, and the spoon.
 * From the Medal of Honor citation for Jonah Edward Kelley:

""So half an hour (after take off) we had to move. We stood up. I had my two hand grenades and I showed everybody I was taking the pins out with my teeth.""

Both are implied to be pathologically aggressive.
