The chap in the photograph is called “Chambers”, despite the freezing cold water and the 15c temperature of the dock he enjoyed repeatedly diving and the adulation it bought him.
I think there are a lot of folks just like the Chambers dude.
We can say he did some things very well. He was getting attention, inflating his ego, and he worked his audience. While he was clearly enjoying the thrill, it was just as clear as he grandstanded for the onlookers...
