Couple of highlights: They wanted him to spray the seat with some Lysol and drive the bus back to the garage. He politely told them to eff off. "We take enough crap during the day. I'm not going to sit on it." Also, despite reports that only the seat was smeared with dog crap, turns out the steering wheel got some, too.
And it may not have been pooch poo, after all: "I think somebody crapped in a Subway bag.... If it was a dog, it would have been a little dried up. It looked pretty fresh."
His recommended punishment for the feces smearer? Some time at the zoo, "cleaning out the elephant stalls."
