Fastest time to husk 3 coconuts using teeth

Martial arts instructor Nguyen Kim Tuan, born in 1963 in Dong Thap province, Vietnam,  began studying martial arts when he was only 6 years old. Since 1980 he began the practice of peeling coconut off with his teeth. He now peels a coconut with his bicuspids without hands in 2 minutes. However, when Nguyen Kim Tuan does held the fruits with hands, he husked 3 coconuts in 58 seconds. Apart from that, he can peel a coconut with bare hands, drag a truck, and hammer nails with his head.
