What follows is quite possibly the greatest, most important Instagram video of all time. Prepare yourself. Ok, you ready?

It's Tom Hanks dancing to (and singing the chorus to, obviously) Montell Jordan's "This Is How We Do It" while dressed as a rabbi.

As if that wouldn't already explode the internet, it was taken by Justin Bieber at Scooter Braun's wedding, which Hanks was at because he's Tom Hanks and doesn't need a reason to do anything. Bieber then posted it to his Instagram, so we could all share in the magic.

90s nostalgia meets movie star meets Justin Bieber, told through social media. Yeah, we're pretty sure the Internet just blew up.
