I like this line, it's direct and a little off the wall, so naturally it appeals to me. It's a little more than just saying hey I like you though, it takes some guts to pull this off, while still looking confident and comfortable in your own skin. There's keeping good posture, and following up the rest of the conversation in a charming way.
I like how he points the one girl out of the three, it shows he isn't just looking for anybody. I wonder how p!ssed off the other two were that no one was hitting on them lol. This is just the sort of thing that would blow up in my face, because the available girl would be one of the other two. By pointing out the one girl, he's kind of narrowing his choices.
The third girl, Amanda, she's there talking to some dude when he approaches her. He's probably lucky that wasn't her boyfriend or husband or something, because he may have gotten punched in the face. Of course, maybe this whole video is fake anyway, who knows?
