This was just posted on youtube, but it’s actually from August 2007. The back story is that TOP was asked to say one of his lines from a drama he was in called “I Am Sam”. The rest of BIGBANG was also asked to say the line. TOP says it like it is in the drama, but a few of the others add their own twist.
I think GD’s reaction after he says it is really funny. I’m not sure if he’s impressed with himself or just really embarrassed. =)
