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.
