I’m goin’ to the movies. Are you comin’ along? I want to see the new movie about the zombies that run a used car lot in the desert outside LA. I think it’s goin’ to be a fantas’ film. They specialize in Hyundais. Most people who go there to buy a car never return. That’s what you’d expect! It is WHY they don’t return that you’d never expect. Well are you comin’? We can take my Hyundai–the one with the blood on th’ back seat. Ha ha! Just kidding!
