Microsoft engineers celebrated the integration of the Surface Pro 3 and OneNote--its note-taking app that rivals the popular Evernote--today. 

They didn't celebrate with a happy hour. They didn't get a pizza party at lunch. 

Instead they created a really super geeky parody song to the song "Sexy and I Know It" by LMFAO, called "Click It and I Note It."

And it's brilliant. I've watched it four times. I'm now watching it a fifth time. 

This is a followup to a parody song that they made in April for when they launched a Mac version of the app called "OneNote Mac," sung to the tune of "One Day More" from "Les Miserables."

Watch out, Weird Al
