"Sometimes a guy’ll be a good guy even if some rich bastard makes him carry a sticker."

– John Steinbeck

The Grapes of Wrath, Chapter 2. Tom Joad cleverly attempts to guilt the truck driver into giving him a ride. He challenges him to be the "good guy" and defy his "rich bastard" employer’s "No Riders" sticker instruction on the truck’s windshield. In other words the driver will be a bad guy if he doesn’t. Tom is appealing to the driver’s sense of humanity and decency. He is also suggesting that working class "good guys" like them should stand together against the rich and powerful "bad guys."
