The fellas in this video are part of the PGA Golf Management program at Campbell University in North Carolina. (That's the program that trains folks to become club professionals, including all the business, financial and managerial skills.) As part of a school competition, they taped themselves - nine of them - attempting to sink nine putts simultaneously. The idea was based on a similar video that came out last year of six students at the Golf Academy of America in Apopka, Florida, simultaneously striking and making six putts. Obviously, the more golf balls you add to the task, the more difficult the task becomes because you are backing away from the cup with each added ball.
