Reminded me of a great story Walton Goggins told on Seth Meyers a few weeks back when he was on promoting Fallout. Apparently, Goggins' dad is quite the character. This is what he basically wears every single day -- with TONS of turquoise.
So he gets noticed a lot. He carries around signed autograph pictures of himself that he gives out to people when they ask him who he is. In addition, he also has pictures of his son Walton, the true famous guy, and offers those as well. (The kicker is that Walton Jr's pics are signed by Walton Sr. I'll see if I can find the portion of the interview because it was the funniest, most endearing late-night talk show interview segment I've seen in many years.)
Found it -- hoping this starts about 6:32 where he says Baby Billy's character/look is partly inspired by his dad. If clip doesn't start there, scrub to 6:32.
