Some millionaires reach seven figures through hustling and penny pinching. Others just get lucky.

Graffiti artist David Choe knows the second scenario well.

As featured on a recent episode of CNBC's "The Filthy Rich Guide," in the early 2000s, Choe's work caught the eye of Sean Parker, founder of Napster. In 2005, after Parker became president of then-fledgling start-up Facebook, he hired Choe to deck out its original headquarters in Silicon Valley with murals.

Though Choe despised social media's early iterations like MySpace and called Facebook a "ridiculous" idea, according to "The Filthy Rich Guide," he agreed to paint the building for a hefty sum: $60,000.

"My prices had been going higher and higher and I was like, 'Yeah, I mean, if you want me to paint the entire building, it's going to be 60, you know, 60 grand,'" Choe told Howard Stern.
