Hilarious Brother Videobombs Sister’s Serious Performance [VIDEO]

As a little sister, I can tell you that messing with my older brother was one of the most fun things in my childhood. Especially because it was so rare!

If I tried to do what this little brother is doing in this video, I would have giggled about 5 seconds in and the whole thing would've been blown.

This Vine was posted to Just Vines Facebook page earlier this week and is pretty hilarious. The sister is trying to film a serious performance of a Robin Thicke song while he brother has a in-shower dance party. Too funny.
