First of all, why would you want to do that? I know it's irritating as heck hearing someone on the phone while you're trying to watch the movie! I wasn't aware of any rules for a school bus. If you leave it turned off and just stashed in your pockets or something, it would be easy to get in. If you're female, then a purse will work. Never seen anyone check for phones at a theater but they kindly ask you to not use them during the movie.
