Continuity mistake: After their encounter with the monks, Buddy and Dave speed off and come out onto a road. The first shot sees the whole car come onto the road, where there is a double unbroken line in the middle of it. The shot changes to Buddy and Dave in the car. Watch through the back windshield. The double unbroken line has turned into a single, broken line. (01:07:35)





Answer: It's really not uncommon for movies to remove bits and pieces when broadcast on TV. Movies aren't just cut for content, they're also cut for timing. (Ex. "Shanghai Knights" used to be absolutely butchered when shown on cable - there were entire scenes missing, which created glaring mistakes.) It's also not uncommon for TV versions or foreign releases to change or remove cultural references, or use alternate takes depending on the language used. Depending on where you live, it could very easily just be that the version you're seeing is one of these alternate versions that was then also trimmed down to fit a TV timeblock.
