If you're looking to make a viral video and you're simply out of good ideas, here's a simple checklist to help you along:
1) The catchiest song of the year (so far).
2) Adorable children.
3) A camera.
In most cases, the kids don't even have to be able to sing, but that's what you'll need.
Of course, when it comes to Pharrell's hit song "Happy," the Detroit Academy of Arts and Sciences choir has already nailed it with plenty of style and talent. Check, check, check, and then some.
You'll just have to wait until a new peppy Top 40 song arrives. It shouldn't take too long.
