Tom Hanks Singing "This Is How We Do It" Dressed Like A Rabbi

    So, Justin Bieber just posted this.

    Presented without comment except what is going on and why is Tom Hanks hanging out with Justin Bieber and I'm so confused right now.

    Important context update: Apparently this is from Justin Bieber's manager, Scooter Braun's, wedding. (H/t Lindsey Weber.)
