Christmas Puzzle

When I share a quote, I like to give credit where it's due. But sometimes it's really, really hard - mostly because so many other people are perfectly happy to share without bothering to mention (or sometimes even to discover) the original source. I wasted a lot of time trying to determine whose quote this is, without ever coming to a satisfying conclusion. It frequently shows up without any name attached. Two of the most common sources cited are Angel Chernoff and Eugene Cho. If you know who wrote this, I'd love to hear about it.
