9. Gladiator Problems

Heading to a costume party in Rome? You might want to think twice about your headgear. One man attempted to bring a spiked Gladiator-style helmet into the cabin, only to have it rejected by security.
While it isn’t a traditional weapon, the metal spikes were deemed a safety hazard. TSA doesn’t take chances with sharp objects, so if you’re planning on channeled your inner Maximus, make sure the armor stays in your checked suitcase.
