In honor of Sesame Street’s 44th season, Jimmy Fallon welcomed the iconic puppets of the children’s show to his set, joining together with the Roots for one of his now-signature singalongs (he’s done similar segments with Carly Rae Jepsen, Mariah Carey, and Robin Thicke).

Vulture recently named Fallon a sort of millennial Johnny Carson, and if you want to know why they’re right, look no farther than this video. It neatly encapsulates every aspect of his appeal to the generation:

1. Winking self-regard. Something about Fallon tells you he thinks he’s the coolest/cutest guy in the room—a look he perfected while frequently breaking character on Saturday Night Live. This is also one of the most annoying things about Fallon, but we supposedly narcissistic millennials don’t mind it so much.

2. Millennial nostalgia. Um, hello, Sesame Street. The show that started everything for the millennials, from our short attention spans to thinking that we’re special. Fallon’s welcoming John Stamos for a Full House tribute is also a good example of this.

3. Mastery of social media. Part of what made Carson Carson is that he was dominant in his medium—broadcast TV. Fallon doesn’t have that luxury. The TV landscape is more fragmented than it was in Carson’s day, and there are plenty of other choices besides: streaming, social media, etc. What raises Fallon above the rest is his mastery of putting together segments in broadcast that go viral the next day on social media, like singalong segments and celebrity lipsynch contests.
