These contraptions were given away by Burger King in Puerto Rico earlier in the year. Apparently as a joke. But that video is no joke.
A device that holds a burger for you - or anything really, you could put chips or a casserole in there - while you're gaming would be for many a must-buy. Even if you could only eat half the burger before having to slurp.
Yes, it's lazy. Horse-like, even. But shut up.
