"So which is is, baby? Spitz or Swallows?" - Austin Powers making a joke about Robin's last names
Her fate is a direct parody of Fiona Volpe from Thunderball. Much like Mustafa, she is almost impossible to kill, even after being stabbed in the back, shot with a machine gun, blasted with a rocket launcher, and falling from a high building. Dr. Evil later says, "Two of my assassins are dead," implying that Robin later died of her injuries.
In a deleted scene, Austin shakes her hand for a long period time to watch her breasts undulate until he ejaculates.
