If not, here's a refresher: Two months ago, the Make-A-Wish foundation sought to make Miles' dream come true and with the unpredicted support of more than 20,000 people, succeeded! How cool is that?!
When Miles first declared his wish, the Make-A-Wish foundation had no idea so many people would rally to help - some even flying across the country - with many, many more following the event online via social media.
Even President Barack Obama Tweeted in support of Batkid because, you know, he wasn't too busy taking selfies that day!
Miles' super day consisted of roaming around San Francisco, saving innocent people and fighting evildoers, before receiving the key to the city directly from the hands of the mayor of San Francisco!
Now, the Make-A-Wish foundation has released an official video of Miles' wish to be Batkid and it's just as touching as you'd expect.
San Francisco has now nothing to worry about!
