Should I stay or should I go?, asks Jean Arthur‘s “Bonnie.” But Cary Grant‘s “Jeff” isn’t the declarative type, so he suggests a coin flip — heads you stay, tails you go. He flips the coin. “Heads — what about it?” he asks. “I’m hard to get, Jeff,” she says, hurt. “All you have to do is ask me.” He gives her the coin, a kiss, out the door, “See ya, Bonnie!” The plane he’s co-piloting with Allan Joslyn is tearing down the runway when she looks at the coin. The scene starts at 7:55.
