Today, Mnet "M! Countdown" was held live.

On this day, Girls' Generation received a trophy for being 1st place with their comeback song, 'I Got a Boy.'

Tiffany showed her happiness and excitement by shaking her hair everywhere. Sunny and HyoYeon, however, had the opposite facial expression on their faces; they were looking at Tiffany with rather grumpy eyes.
