Tonga Fifita—also known as King Haku or just Haku—is no joke. He was one of the toughest to ever step foot inside a WWE ring. He also bit the nose off a man who called wrestling fake, so he's not to be played with outside of the ring either. But Tonga is also a charitable family man, which is something his nephew Dwayne "The Rock" Johnson can attest to.

The Rock's story of rising from being dead broke and becoming a superstar is no secret. He retold part of it on Instagram when he shared that he bought Tonga a new truck. The post showed the two posing with the truck, an old picture of The Rock wrestling in tight purple trunks, and Tonga in his intimidating prime.

There's a lot of stunting and aggression here, but there's an emotional story behind it. Gather 'round:

 I get a call from WWE saying "Vince McMahon wants to see you wrestle immediately. He's flying you to RAW tomorrow and you'll have a tryout match." I thought holy shit that's awesome, buuuut there's a few problems: For me, I wasn't just having "a tryout match", because I had never actually HAD a real match in my life. Ever.

WWE thought that I already had multiple matches under my belt, but little did they know. What they also didn't know was that I was broke as hell and didn't actually own wrestling gear - no boots, knee pads or most importantly.. wrestling trunks. I went to Sports Authority and bought some bright ass white volleyball knee pads, called my Uncle and asked if he had ANY trunks I could use for my tryout. He said all I have is a pair of shiny purple trunks (purple was his signature color), I told him I don't care if the trunks are all the colors of Skittles, I'll happily wear them.

When I picked the trunks up from him I'll never forget the monster hug he gave me, look me in the eyes and said, "I'm so proud of you. Go get 'em nephew!" Here's the picture of me wrestling my FIRST MATCH EVER in Corpus Christi, TX in front of 15,000 people - proudly in my lucky purple trunks. And the rest... was history.
