OMG.  First the got beef video and now this.  Why am I so ashamed that I unsderstood those two videos (and the got beef) but kept watching the second because of the girls.
EDIT:  They're viet, omg why did I have to understand.
If any of you are curious, what he says when he says I'm number one, what follows translates roughly into cute and handsome (seperately, not a word that means both).  So, I'm number one at cute and handsome.
EDIT2:  THe first video is an award show, though probably not at all but a show and those guys were just distracting the audience while they changed probs/singers/costumes.  The Cai Luong is a type of music (featureing the stringed instrument in the background I forgot the name of) and Tieng Anh means english.   So, redneck vietnamese music sung in english.
