Silly to make two posts, so here are two videos.
The first i've watched at least 10 times now and it keeps maing me laugh.

The second I just find pretty amazing. Even if you are not familiar with the song, you really have to appreciate the work that went into chroeographing this. It's 3:44 long, and I highly recommend watching the whole thing. Though I would tell you to load the page and hit pause right away, let the whole video load. The good parts do not start until 50 seconds into the video.
