Praline: Hello, I wish to register a complaint . . . Hello? Miss? Shopkeeper: What do you mean, miss? Praline: Oh, I'm sorry, I have a cold. I wish to make a complaint. Shopkeeper: Sorry, we're closing for lunch. Praline: Never mind that my lad, I wish to complain about this parrot what I purchased not half an hour ago from this very boutique. Shopkeeper: Oh yes, the Norwegian Blue. What's wrong with it? Praline: I'll tell you what's wrong with it. It's dead, that's what's wrong with it. Shopkeeper: No, no it's resting, look! Praline: Look my lad, I know a dead parrot when I see one and I'm looking at one right now. Shopkeeper: No, no sir, it's not dead. It's resting. Praline: Resting? Shopkeeper: Yeah, remarkable bird the Norwegian Blue, beautiful plumage, innit? Praline: The plumage don't enter into it -- it's stone dead.
