Trivia: Steve Buscemi remembers how he was cast in this film: He was in the men's room when writer-director Quentin walk in and went to a stall. It was then that Quentin told Buscemi, 'Oh, I cast you as Mr Pink.' And the rest, as they say, is history.
Trivia: In a deleted scene (available on the DVD), Nice Guy Eddie considers taking Mr. Orange to a nurse named Bonnie. 'Pulp Fiction (1994)' also features a nurse named Bonnie.
Chosen answer: Having just been shot a second time, he was probably dying by that point. He'd done many extremely questionable things - even murdered an innocent mom - and stood by as other terrible crimes were committed in his presence. He'd grown close to Mr. White, who'd just murdered two friends and taken a bullet for Orange's sake - even as Mr. Orange was betraying him all along. So partly this was about his attachment to Mr. White, and partly a death wish stemming from his own guilt about his actions. He knew full well what would happen but told Mr. White anyway, disregarding the consequences.
