Mood rings were invented in the 1970s and they're still going strong. We love it when customers get excited about seeing what mood they're in, and when asked how they work, we always reply — it just knows how to read your mood. (Trivia note: the same man that invented the mood ring went on to invent the Thigh Master Exercise Machine!)
