I’m not sure if I’ve been under a rock for the last 5 months or what because I’m not sure how I missed this video. It’s hilarious!

With the episode we’ve all been waiting for coming up this Sunday, I thought it was fitting to post this here as well.

Jimmy Fallon plays a sound guy for ‘This Is Us’ and just can’t keep it together during a scene between Sterling K. Brown and Chrissy Metz’s characters. It’s all of us watching the show every week and the ending is hilarious.

Good luck not crying this Sunday, America!
