Milo Murphy's Law: First episode premiered on Youtube! · 9:11pm Oct 1st, 2016
Disney XD has uploaded the first episode of Milo Murphy's Law to their Youtube channel. Since this is a legit video from the copyright owner, I'm linking it.
It's only available to viewers in the US and possibly Canada as far as I can tell. I've confirmed with Zef it doesn't work in Mexico.
But hey, if you can't wait two whole days to check out Dan and Swampy's new show, here you go!
