Just imagine for a moment that you are the director of a movie, or producer of a show. You write scripts for movies and tv shows, and your ideas were casted onto screens everywhere.
So naturally, seeing as you are responsible for writing up these scenarios, you can get away with slipping an inflation/expansion scene of any sort into your production. Of course, it will have to make some sort of logical sense to the context of the show. But if it works for plot, a gag, or whatever sort of visual effect you're trying to achieve, then make it happen!
