Best Bus Stop Ever (VIDEO)

And this week's award for viral marketing goes to... Emeli SandeHilary MantelQualcomm.

The wireless technology company created a lovely little set-up whereby people waiting at a bus stop saw a poster ad for their services. And if they did as the advert instructed, then... well, we won't spoil the surprise for you. But it's safe to say that they got pranked in the nicest possible way.

Of course, what the video doesn't show is that each person in question then had a massive charge for the surprise event added to their mobile phone bill. NOT REALLY!
