Matt Damon's opening monologue took a sweet, serious turn when he hosted Saturday Night Live on Dec. 15, and the emotional moment delivered a much-needed dose of positive vibes before the season finale even got started.

The actor is no stranger to the show, having hosted once before in 2002, and he poked plenty of fun at himself and his Bostonian upbringing (and Ben Affleck, too) while sending love to his hometown. (He later reprised his role in a sketch that had him dusting off his career-launching starring role from 1997's Good Will Hunting.)

But the warm-and-fuzzy part when Damon talked about watching Saturday Night Live with his father and brother as a kid. "He told us if we could stay up 'til 1 a.m., we could watch Saturday Night Live," he said. "So week after week, I tried to stay up, and it wasn't until I was 8-years-old that I made it all the way end. I probably didn't get all the jokes, but I laughed at everything my dad laughed at. Although it was way past our bedtime, my dad knew that there was nothing more important in the world than to laugh with the people that you love."

Damon then shared that his father passed away around this time last year, that his brother was watching the show right then with his family in Boston, and that his children were there with him at SNL. He added his youngest daughter -- who's 8-years-old -- came to see him perform on the show that night.

He closed his monologue with a toast to the viewers at home: "Here's to all the moms and dads who let their kids stay up too late for all the right reasons."
