A video that went viral a few years ago is making a comeback -- and it's hilariously genius!

These high school students came up with the idea of what it would be like for a group of monks, who have taken a vow of silence, were to sing  Handel's "Hallelujah Chorus".

When I was in high school, I was member of our school's award winning honors chorus, and performed this song, many times, in front of thousands of people. Technically, it is incredibly difficult to sing. I can't imagine what it was like to choreograph this little number with the silent monks!
