Interrupción en el continuo espacio tiempo (2006)

A disgruntled, middle-aged man arrives home to his prim and proper wife with a headache. A stale, mundane conversation ensues. She fetches him an aspirin. As the man unwinds from his day, he hears a door slam and a man's voice coming from another room. Upon further probing, the husband is aghast to realize the conversation playing out downstairs is the one he just had with his wife and he's the one talking to her.
