What is Underwater Basket Weaving?
Underwater basket weaving is an idiom referring in a negative way to supposedly easy and/or worthless college or university courses, and used generally to refer to a perceived decline in educational standards. The term also serves as an intentionally humorous generic answer to questions about an academic degree. It is also used to humorously refer to any non-academic elective course, specifically one that does not count towards any graduation requirements.

This website is entirely dedicated to the subject of underwater basket weaving along with promoting awareness and conserving the sport. While many people think this is a joke, it should be taken seriously (sarcasm).
Without public awareness of this amazing sport, the joke will die out and people will definitely miss out on this.
