Just in case you're younger than I am (this song was released in 1984!), here's the original video from Lionel Richie.
And, I can't take credit for this funniness. People magazine jumped on the bandwagon before I did. So, I guess I'm just a poseur.
IMPORTANT UPDATE: Just for kicks, I watched the Lionel Richie video again (I hadn't this morning when I posted it) and was reminded how creepy the video is. Talk about inappropriate teacher conduct toward a student. And like any good person these days, I looked up "Lionel Richie Hello teacher student" online. I found this link, which I think you should visit.
