This billboard makes you yawn then gives you free coffee

The Contagious Billboard
Brazilian coffee company Café Pelé (yes, named after the footballer), has created a billboard that makes you yawn, and then gives you free coffee.
The billboard was put up in the São Paulo Metro with tracking hardware, the more people near the billboard the more it yawned and the more free coffee they gave out.
Work by Lew’Lara\TBWA, Brazil.
