chunk: It is 1963. Ernest Tilley (Danny DeVito) and Bill "BB" Babowsky (Richard Dreyfuss) are door-to-door aluminum siding salesmen in Baltimore, Maryland. Working for different companies, the "tin men" are prepared to do almost anythingâlegal or illegalâto close a sale.
  Their first meeting is when BB buys a new Cadillac and almost immediately crashes into another Cadillac driven by Tilley. The accident is caused by BB, as he reverses into the street from the dealer's forecourt. Tilley, though distracted, clearly has the right of way. Each vows to get even.
  After they smash glass on each other's cars, BB takes it a step further. He sets out to seduce Tilley's wife Nora (Barbara Hershey) as an act of revenge. When he calls Tilley immediately after having sex with her, Tilley tells BB to keep Nora; he wants to be rid of her.
