Factual error: This film takes place in the early 90's. When Walter and the Dude are talking about the toe in the cafe, you can see late model cars driving by on the street, such as a late model Ford Explorer and a Cadilac. This is also evident when the Dude gets kicked out of the cab and a mid '90s Nissan Maxima drives by.

Continuity mistake: The Dude's driver's-side door is unusable after his car is stolen and retrieved, and we see him using the passenger door at least once after he takes the car home. But then at Larry Sellers' house, which they visit pretty soon, The Dude gets out of the driver's door as if nothing had happened; I doubt he'd have bothered to have it fixed in that short time. (01:09:00)
Walter Sobchak: Shut the fuck up, Donny.
Trivia: This isn't really a mistake, just something to note - throughout the whole movie the Dude is not seen bowling once. Also, every time you see Donnie (Steve Buscemi) bowl, he gets a strike, except for the last bowling scene, he does not get a strike, and he dies of a heart attack a few minutes after this.
Answer: Generally, he means that the boy, Larry Sellers, is disgracing his family (Walter has huge respect for the boy's dad, but considers the kid a dunce). Specifically, Walter is blaming Larry for his father struggling to breathe; that's Larry's dad in an iron lung in the background. Walter and The Dude become louder, more insistent and more vulgar, but the kid still blankly refuses to answer, and all you can hear is the iron lung pumping in the background. Frustrated because the kid isn't intimidated, Walter lashes out: "You're killing your father, Larry!"
