Who has time to hold the burger while eating it?

Burger King has finally come up with a solution to that most vexing question that has plagued mankind for decades: "In a world of multitasking, how can you use your hands to do daily activities and eat a Whopper at the same time?"

Enter the hands-free Whopper holder, a plastic device that hangs from the neck and places your Whopper inches from your mouth. All extraneous movement has been removed from the burger-eating process, including the act of bending your arms to bring the sandwich closer to your mouth.

With both hands released from the restrictive and calorie-wasting act of food eating, Whopper lovers are free to perform all of their favorite or pressing tasks while enjoying the flame-broiled goodness of Burger King's signature sandwich.

Now, if only McDonald's can come up with a device to chew our french fries.

The fast-food chain told CNBC Tuesday that it gave away 50 Whopper holders to its "50 biggest fans," in celebration of its 50th anniversary in Puerto Rico, and there are no plans to distribute them nationwide.

Ad tracking firm Creativity Online said Tuesday that Burger King's advertising agency of record DLC/Olgilvy & Mather produced a promotional video about the hands-free sandwich holder released on YouTube that made the internet rounds in the last few days.

The humorous spot, featuring the burger-eating technology breakthrough, shows Whopper-eaters playing guitar, trimming hedges, ballroom dancing, painting their finger nails and using nunchucks.

Burger King confirmed to CNBC in a brief statement Tuesday that the Hands Free Whopper was purely a promotional event and will not be distributed to the regular Burger King customer. BK and its ad agency declined further comment.
