Observe the birth of the New Year, and record it so you can embarrass the year when it’s older. Give the New Year its first bath. Join it in the bath. Record that too. Try to determine whether it’s a boy or a girl, and then debate about it with yourself. Then debate about what difference it makes.
Optional: Do all the above with family, friends, and complete strangers. In honor of the newborn year, celebrants should wear only what they wore when they were brand spanking new on their true birthdays. Whether or not the celebration be held inside or out depends mostly upon the amount of celebrational lubricant present.
This is also known as Birthday Suit Day, which can be celebrated on your or anybody else's birthday.
