I can't believe I didn't hear this before! But around 3:53 as Park Bom is about to sing, you can hear G-Dragon quietly saying his lady's name, "Park Bom!" This was on their forst performance of "Oh Yeah" on Dec. 19, 2010. So on their next performance, GD you better say your lady's name louder for everyone to here, aighht?

Here is another video link of jus 'Oh Yeah' & without ads on youtube.
