Ok, I looked it up and there's debate on eggs. There really is a bagging competition though:

The National Grocers Association (NGA) Best Bagger Championship is an annual competition that tests grocery baggers on speed, technique, and style. Contestants bag identical orders of up to 40 common items using reusable bags. Judging is based on a point system, with 10 points possible for speed and 10 for bag building technique
