Running late for my wedding, I realized I had no laces for my shoes. I ran into a shoe store with shoes in hand. Shouting over the heads of the other customers, I yelled, "I'm supposed to get married in five minutes, and I need laces." The clerk reached under the counter and tossed me a set.

"How much?" I asked.

"Forget it," the clerk replied, "You're already paying a price for that knot!"
