A perfect pair

They're tailor-made. The silly giggles match properly. The ugly thoughts heavily fit. The extreme incompetence plainly corresponds. The hostile micro-management closely reflects. The stuck-in-the-past garments horribly echo. Still, style is obviously lacking. They're a muttering, bickering match. They're ugly and their mom must have dressed them funny. They're costly and their dad must have fed them envy. They're perfectly suited for the purpose. They'll agree to service any demand or requirement, as long as they think it'll keep the sugar coming. They're cheap, in a custom way.
