Random is a word bandied about a lot by d'interweb folk but really it's the only word applicable for the video below.

For your humble viewing, here's a video of Tom Hanks, dressed as a rabbi, singing “This Is How We Do It”, courtesy of Justin Bieber.

The footage, published via Instagram, was taken at the wedding of Bieber's manager Scooter Braun.

The caption reads: “Haha Tom Hanks singing “This Is How we do it” dressed like a Rabbi lol #thatdancetho”
