Word to the wise: When a (possibly racist) 67-year-old man wearing an "I AM a motherfucker" t-shirt gives you guff on an Oakland bus, just let it go. Or go home and get your shine box.
Update: The plot thickens. "Epic Beard Man," as the internets have now dubbed him, MIGHT also be Thomas Bruso, a.k.a. "Tom Slick", a.k.a. the guy who got tased at an Oakland A's game last year. The man's violent past makes the story more intriguing, but the web's casual racism makes it less funny.
