T-Mobile Reinvigorates the Flash Mob

T-Mobile has been pulling some cool stunts lately. Most recently, they had a group of performers take over Terminal 5 of London’s Heathrow Airport to greet tired travelers with a song and dance. It's all part of the brand's “Life’s for Sharing” campaign, and judging by passenger reactions — and 26 million views on its YouTube channel — T-Mobile is nailing it. Will flash mobs ever get old?
