Remember the 80's movie "Splash"? Tom Hanks asks mermaid Darryl Hannah her name, and she says she doesn't have one. He asks her to pick one, and she sees a street sign for Madison avenue and says "That's it! Madison!" He laughs and says that it's not a first name, it's a last name. She starts to cry, and he shakes his head, rolls his eyes and says, "All right. Your name is Madison," as if it's the dumbest thing ever.
Now I know about 6 couples who named their daughters "Madison."
