Analysing the video: Chromeo, Don't turn the lights on

This is a quite cool song by a Canadian group called Chromeo. Watch and see if you like the beat.

Here are the top things about this video for you to check:

1-The singer ears.
2- What the hell is that guy spotting grapes?!
3-Everyone is wearing eyeliner.
4-Around 1:00 min you can see people sword fighting in the library (huh?).
5-The person appearing at 1:41 drinks too much coffee/tea.
6-When the singer smiles/spreads his teeth in the dark he looks just like Ronald McDonald (the clown). Creeepy.
7- SPOILER: At some points both guys become different people. I actually only noticed the singer becoming another person, but the keyboard guys gets replaced too. My eyes were so directed to the main focus in the image that I had to watch it other times to realize that the co singer becomes another man.
