Summer Olympics, 8 p.m., NBC
Tonight, Track and field, finals: men's 4x100m relay, men's 5000m, men's javelin, women's 4x400m relay, women's 800m, women's high jump; diving: men's platform final; volleyball: women's final. My 11-year-old is obsessed with the divers jumping into the hit tub after each dive, and emerging with the ShamWow. He keeps asking, ‘why?’ and I keep saying, ‘because it is there.’
