SHELDON: "We do not celebrate the ancient pagan ritual of Saturnailia. In the pre-Christian era, as the winter solstice approached and the plants died, pagans brought evergreen boughs into their homes as an act of sympathetic magic to guard the plants and preserve their essences until spring. This custom was later appropriated by northern Europeans and eventually becomes the so-called Christmas tree."
HOWARD: "And that, Charlie Brown, is what boredom is all about."
