It should go without saying, making any kind of jokes or off-color comments which could affect the safety of others is a definite no-no. Even if you’re joking out of nervousness, you could end up being arrested or at least removed from the flight. Nowadays, any type of comments regarding weapons or safety are taken with the utmost seriousness. Flight attendants do have the authority to remove you if they feel you pose even the slightest risk. In the world we live in, with all that’s happened regarding safety and acts of violence, it’s best to keep your comments to yourself. If you feel you must entertain others to get attention, an airline flight should be your last choice for an audience. Go to your local comedy club and try your jokes there. You may get thrown out, but, chances are it won’t be for a safety violation!
