Meet the WWII veteran, age 91, who can pull a car with his TEETH

Mike Greenstein is giant of a man. He can pull a truck uphill using only his teeth. 

They call him the Mighty Atom Jr and he has perhaps the strongest jaws and neck in the country.

But at 5-foot-4, this 91-year-old Second World War veteran is a surprising powerhouse.

Strongman: Mike Greenstein effortlessly drags his 2006 Buick down 48th Street in New York City -- after reminding the guy behind the wheel to take his foot off the brake

Determined: Mike has been pulling cars with his teeth since the Second World War and has perhaps the strongest neck and jaws in the country

To celebrate the Fourth of July, he demonstrated that he still has teeth of steel by dragging his Buick down 48th Street in midtown New York City live on Fox News.

When he first took hold of the leather bite pad, which he made himself 75 years ago, and began tugging on the chain, it didn't look good for the elderly showman. The 3,800-pound Buick didn't budge. 

 

'Take your foot off the brake,' Mike says. 

The car free, he tries again. With the leather clenched between his teeth and a determine snarl on his lips Mike begins to move backwards, step by step. 

Small package: Mike is just 5-foot-4 and is now 91, but he is still capable of incredible feats that would unimaginable for almost any healthy young man

It's slow at first, but then he gets going. 

During an exhibition for the New York Times last months, Mike stopped his mailman, who had come by his house in Queens, New York, on his daily rounds. 

He hooked a chain to the mail truck and, with an audience of only a reporter and the letter carrier, slowly dragged the vehicle up a hill with his teeth.

But that wasn't enough for the consummate showman. 

Tool of the trade: Mike uses a leather bite pad he made for himself in 1939. It has an indentation for each tooth

He was pulling his Buick around the parking lot of his apartment complex when got a little too excited. He pulled the car so fast, it slammed into a neighbor's parked car.

'OK? Not bad for a guy with a handicapped license plate,' he told the Times. 

Mike is a guy who can cause car to crash using only the power of his jaw. 

The showman style and absurd strength runs in the family. 

Runs in the family: Mike gets his incredible strength from years of training with his father, Joe Greenstein, who was called 'The Mighty Atom

Mike is the seventh child of Joe Greenstein, the original Mighty Atom, who was one of the last great Vaudevillian strongmen. 

From a young age, Mike followed his father around the country and learned the family trade. 

When he served overseas in the Army Air Corps during the Second World War, he began his performance career -- showing off the his fellow soldiers by pulling a truck full of troops with his teeth. 

At 91, the years have begun to take a toll. He had a bad shoulder and doesn't have quite the energy he used to. But his teeth are still strong.

He makes sure to take care of them each day by brushing them with Kosher salt, just like his father taught him.
