Let's talk about the video for Justin Bieber's 'Yummy'

This video is...interesting. I did not expect this style when I listen to the song, but hey, it's entertaining! Bieber walks into a restaurant (from the kitchen), sits down, and then we see delicious food like fries, lobster, sandwiches. I wonder if some of the food is a nod to Hailey and their relationship. The dining room then turns into a club and it looks like a good time.

What's up with his chin though?
