Does anyone know the youtube animated clip about love and heartbreak?

There is this clip where a teenage guy's heart starts beating when he sees this girl, then he takes it and hands it to her, but she just drops it in the mud. Then he falls for another girl, and she takes it and steps on it. Then the next girl takes it and rips it. Finally he gets so fed up that he drops the heart on the floor and steps on it, leaves it there, and walks away. In the end a girl with a broken heart starts to beat for him. Does anyone know this clip? I really want to find it.
