Hahahaha, when they scream <3
And when Niel went "Oh, Zebra L.Joe" and L.Joe pushes/hits him xD Hahaha bromance ^3^ And how they said in the video "Zebra (x), Leopard" LOL xD

But there is one thing that I'm wondering. When they perform live, and sing.. they can't be doing these noises in the background, right? Soo.. how can they still be so awsome performing live? O__o hahaha I bet you that they yell like this in their heads while performing xD
