I See Jesus in LA
If you've ever been walking down the street and been like, "Holy Hell the Lord And Savior is right in front of me" then you've seen I See Jesus In LA, (aka Hollywood Jesus) who's actually a dude named Kevin who dresses like Jesus and walks around LA. If you saw Jesus and took a picture, you can submit it to the "official" Tumblr, "I saw Jesus in LA." He seems to make his way to concerts, sporting events, and cultural events regularly, and -- though he dresses like the world's most famous poor man -- by all accounts he's doing pretty well, since he drives a Mercedes and has appeared in multiple videos by (of course) LMFAO.
Silver Lake Walking Man
It would be impossible to finish this list without a hat tip to Silver Lake Walking Man, aka Marc Abrams, who sadly passed away a few years ago. The subject of murals, a documentary, and tons and tons of fan tributes, the ultra-gaunt Abrams walked around the Eastside for miles (and miles!) at a time, shirtless, reading, and saying hi to people; when he died, many people learned he was actually a doctor who just loved walking. Walk on, man.
