10. The Sword Collector

It seems some travelers missed the memo that swords are, by definition, weapons. An aspiring knight was stopped at the X-ray machine with an entire collection of blades in his carry-on bag.
Needless to say, the collection was confiscated. Swords are never allowed in the cabin, regardless of their historical value or “coolness” factor. Had the collector simply checked his baggage, he could have kept his arsenal.
