Dreading holiday travel? We don’t blame you, it is already starting to get crazy. Today, TSA caught a passenger flying from Washington DC to Chicago trying to smuggle two throwing knives inside of a hollowed-out book.

The knives were hidden in a copy of Ninja: The Shadow Warrior. According to The Daily Mail, “Written on the opposite page to where the knives were discovered were the words ‘concealability encapsulates the ninja philosophy.”

The Daily Mail has more: “Security staff at Reagan-Washington airport discovered the knives, which measured over half a foot long, on Monday, in a hollowed out book about Japanese ninja warriors hidden in the man’s carry-on bag.”
