This is Us star Milo Ventimiglia is such a generous artist! After all, you need to be quite generous if you’re going to surprise fans while your hit show is filming on their neighborhood property!

Thankfully, Milo filmed the whole thing on Twitter — as he walked by a house, he noticed the family inside was watching the show! So he and his cast mates thought it necessary to crash the party.

Watch, and gain a whole new respect for the amazing Milo:
