Anna Kendricks song "Cups" is a great tune, but this couple take beverage holders to a whole new level.

Check out this clip of Tchaikovsky’s ‘Sugar Plum Fairy’ played on glasses.

It’s pretty cool and definitely a unique take on any song.

Who knows – maybe this will become a trend. ‘Blurred Lines’ on glasses? That doesn’t work in the dishwasher, but it sure could be pleasant on the ear.
