When Luke and Michelle are in the couch discussing Haley losing her father, there's a fly that won't stop crawling around Luke's hands. He subtly tried moving his hands and readjusting his body without interrupting the scene, the fly was relentless and wouldn't leave him alone.
A sprint coach mentions a "100 meter dash" race, but just before being interrupted starts to talk about a "500" - no track sprint race is over 500 anything, the closest being 400 meters (5000 meters is raced too but anyway is not a sprint).
