I went through a brief and ill-advised period in high school where I thought it would be fun to learn how to golf. There was a course near my home where I went a couple times to play 9 holes with my old neighbor. Whenever we would pay, the total for both of us would be $19.45. Every time we went, the same old guy would charge us and when the $19.45 price popped up he'd say, "Good year for the allies." In spite of being nearly done with high school, I never had any idea back then what he was talking about.
