Family goes twerking mad during hilarious Christmas dancing challenge

A family took part in a hilarious challenge game over Christmas, where competitors had to shake ping pong balls out of a box strapped to their lower backs, and worked themselves into a frenzy.

The game, called "Twerk Pong", was played by a family from Jamaica Plain, Boston, Massachusetts on Christmas Eve 2018, and is a race between two players to shake their boxes empty in 60 seconds or less.

A variety of moves, gyrations and flailing hops were tried to varying degrees of success while everyone seemed to be having a great time.
