worst. idea. ever.

LONDON (Reuters) - Tired of the same old lunch at your office desk? Help is at hand. A British supermarket is launching the ultimate life-enhancing snack -- the musical sandwich.

In a trial certain to be welcomed by the estimated one million Britons who eat their lunch at their desks each day, Britain's biggest retailer Tesco will use technology similar to that used in singing greetings cards to sell musical sandwiches.

Opening the top of the sandwich box will activate a tiny sound module that plays a selection of music. This season's offering will be a medley of Christmas tunes including Jingle Bells, Santa Claus is Coming to Town and We Wish You a Merry Christmas.

ummm... have they ever heard those musical greeting cards? this promises to be the most annoying invention since the furby, and a new source of workplace violence.
