Por qué matan las mujeres

Every episode title in Season 1 is a parody of a movie line or catchphrase. Every episode title in Season 2 is named after a 1940s or 1950s film noir.

The opening credits for season one are animated in a comic book style and feature women from different time periods killing their husbands for various reasons. The song "L.O.V.E" plays for ironic effect. (1) A man in the 1950s is drinking and smoking in the bathtub. His wife, annoyed by his boorish habits, enters the bathroom holding an electric fan. She plugs the fan into a nearby socket and tosses it into the tub, electrocuting her husband to death. (2) A 1920s man yells at his wife. The woman, fed up with his verbal abuse, pushes him down a flight of stairs. The man dies at the foot of the stairs, having broken his neck from the fall. The woman, initially shocked at the outcome, soon smiles at the idea of ridding the world of her insulting husband. (3) A couple in the 1990s is celebrating their anniversary with a romantic dinner. The husband pushes a present towards his wife. After opening it, the wife is angry and offended to learn it's a clothes iron. She hits her sexist husband on the head with the iron and he dies of blunt force trauma. The woman then finishes her meal. (4) In the 1980s, a man is watching sports on TV. He is shouting, eating messy food, and wiping his hands on the chair he's sitting in. His wife enters behind him; she is sick and tired of his slovenly ways. She pours gasoline around her oblivious husband, lights a match, and throws it onto the gasoline trail. She watches in twisted delight as her slob of a husband burns to death. (5) In the 1970s, a woman in a car sees her husband kiss a younger woman. Furious at his infidelity, the woman drives her car toward him. The husband tries to run away, but is hit by the car. He is sent flying and lands on his head, dying immediately.
