Haha, onew.. All the falls and his voice cracking up ^^. But truth is that he has an amazing voice. When you hear his voice crack up like that you know that he sings for real. And always tight before his voice cracks up he sounds great!!!! Then at 3:50 when Jonghyun dosen't sing in to the mic, SOOO cute! Or when Taemin actually caught his at at 4:16, that's impressive ;) haha :D

Update: Hahhahaha, when Taemins voice cracks up at 5:54. SOOOO cute!!!! And it kinda sounds like when goofy laughs ^^
