The Rock is a legit 6'4"
He stood next to my 6'3" friend and he appeared to have an inch on him.
He's a really nice dude, and seemed genuinely interested in what we had to say for just stopping him in the street. I was actually the one who had to break off the conversation because I knew he and his entourage had someplace to be.
Every Samoan I've met acted very humble and polite.
