The 39th annual International Whistler’s Convention is now in full swing in Louisburg, N.C., the self-acclaimed whistling capital of the world. The competition lasts for five days and is full of interesting rules and regulations: whistlers enter the contest in three categories — Classical, Popular, and Allied Arts (in which a performer can combine whistling with other talents, such as miming, singing, or drama) — and are expected to follow a Whistler’s Code of Ethics. 

Louisburg College is an official supporter of the convention, and there are some great images from the event over the years in their student yearbooks on DigitalNC.org. Whistling may be a serious business, but it certainly results in some pretty funny faces.
