Quote from Sally in A Nightmare on Dick Street: Part 1
Tommy: You can't marry her. You're not even the same species. Dick: She doesn't know that. As far as she knows, I'm like everybody else. Sally: And eventually she'd figure out you're not like everybody else, and then she and I would have to go for a little "walk." Dick: You wouldn't. Sally: Sure, Dick, of course I wouldn't.
