This is a LUVs commercial called "New Kid" from 2009 that I only saw for the first time today. It's over a minute long so I'm not sure if and where it ran, but I'm hoping it's the first time most of you see it too.
Then we can all forget that it's an advertisement and you can pretend I just gave you the gift of the funniest video you have ever seen.
Also— Mazzy? I'm so sorry.
