'Call Me Maybe' Olympic Style

A friend of mine posted this on Facebook in August.  I tried to share it then and it didn't work.
But, I was just thinking about it the other day and wanted to finally share it.
Every time I hear this song I picture these guys.
It makes the song awesome instead of annoying.

I want to:
1. Know how they did it.
2. Be friends with the entire team.

I hope you enjoy it as much as I did!
