Action man Dwayne Johnson's family members were tough Samoans - his grandfather once bit a fellow wrestler's eye during a hotel brawl.
The Scorpion King star has had his own famous bouts in the ring, but he has never hit the headlines for scraps outside of the wrestling arena.
His grandfather, who was also a top wrestler, was always fighting - especially when someone disrespected him, his family or his roots.
The movie star explains, "My family is known as being one of, if not the toughest, in wrestling; when they would get in fights... somebody's nose would be gone... an ear would be gone.
"There was this one time my grandfather was eating. He was on this tour, wrestling... and one of these wrestlers was making fun of him, how he was eating with his hands.
"They wound up getting into this huge fight that wound up going from the hotel restaurant, through the hotel lobby... through the window... out in the streets.
"The guy wound up hooking my grandfather... so he tied up completely (couldn't move); my grandfather bit his eye out."
