Quote from Carla in The Spy Who Came In for a Cold One
Carla: Hey, if you're in the mood for gum, I can get you a fresh stick. Eric Finch: Actually, I was looking for bugs. Carla: Try the blonde girl's hair. Say, you're from England, huh? Eric Finch: How'd you guess? Carla: Well, because you sound smart even when you say stupid things.
