Some of the best tennis players in the world were no match for these enthusiastic ball boys. Venus Williams took on two-time Grand Slam winner Svetlana Kuznetsova in a recent friendly match in Auckland, New Zealand, but a trio of four-legged ball boys completely stole the show. Ted, Oscar, and Super Teddy—a bull mastiff, border collie, and Jack Russell-Norfolk terrier-miniature schnauzer mix, respectively—are, according to the ASB YouTube channel, "the cheekiest ball boys (dogs) in the world."

With retrieving tendencies hardwired into their genes, we have to ask: Why aren't dogs always used as ball boys? We'd tune in to see that.
