Kim Kardashian decided to throw it all the way back to 2012 on Monday with a short clip of her and Kanye West's first date. The clip, which is available in full via Kim's app, show's the pre-marriage couple dropping some historic moves atop the equally historic FAO Schwarz piano:

"This video was from when Kanye and I went to FAO Schwarz and played piano together," Kim explained when sharing the video with her followers. "Our friend Joyce Bonelli took the vid. This was actually one of our first dates!" As some cursory Googling shows, this date most likely took place in April of 2012, perhaps even on the exact same day that TMZ reported seeing the eventual couple exit Serafina before they were promptly "swarmed by the biggest army of photographers we've seen in a long time."

Of course, so much has happened in just four years. North West, the couple's daughter and first child, was born in June of 2013 to the immediate joy of Twitter and the 'gram. Kim and Kanye were then married in May 2014 in an impossible-to-emulate ceremony in Florence that awesomely included the Batman-nodding presence of Jaden Smith. In December of last year, Kim gave birth to her and Kanye's son Saint West.

Now two months old, Saint West made his worldwide debut last week on Kim's 'gram. "Today is my dad's birthday," Kim wrote when first sharing the picture via her app and website. "I know there’s nothing more in the world he would have wanted than to meet his grandchildren. So I wanted to share this pic of Saint with you all."
