You've probably noticed that every pair of blue jeans has an extra little side pocket sewn in above the right-hand pocket.
You may have heard this called a “watch pocket,” a vestigial sartorial left-over from the days of pocket watches.
Don't believe it. Here's the real story.
Among the ancient Norse, for obvious reasons, it was customary to carry a small image of one's luck-god on one's person. This hlutr-god (hlutr is cousin to English lot, as in drawing lots) would be suspended from the belt in a little pouch of its own.
(Possibly the most famous story about a lot-god in the lore is that of Einarr Skálarglam. Einarr, a Norwegian, was considering a move to Iceland, but hadn't yet made up his mind. In the meantime, the little silver image of his luck-god Frey, which he carried with him at all times, disappeared. Frey appears to Einarr in a dream, and tells him to settle in Iceland after all. “When you dig the hole for your house's king-post, there you'll find my hlutr,” he tells him. Of course, everything turns out exactly as the god says.)
(Incidentally, Einarr's descendants still live on that same farm in Iceland.)
