MBK exposed?

On this past Saturday morning at about 1pm, I got on the 71 outbound at haight and stanyan. Quickly, I realized that the bus driver of the day had a lot of personality, because he kept singing and whistling; also, he was calling out stops verbally. He stopped to talk to a meter maid out the front door of the bus, a conversation that lasted a few minutes. He kept offering up wisdom and anecdotes to life, although I'm still not sure exactly to whom he was speaking that whole time, I mean he was probably just talking to nobody in particular. 2 kids tried to sneak on the bus, but he drove off and said, "Joo wanna play games, we can play games," while laughing. About 5 minutes later, he ran out of the bus and chased 2 people halfway down the block- he said something about them writing graffiti on the bus. So now we know, MBK is a white guy with glasses, and he is accompanied by a 5 year old Mexican boy.
