TheFineBros, famous for their "Kids React" and "Teens React" web series, dropped a new "Do They Know It?" video on Thursday, September 10, and the results will make you feel like a grandparent.

In the vid, kids listen to theme songs from popular '90s cartoons like Cartoon Network's "Dexter's Laboratory" and Nickelodeon's "Rugrats." MTV's hit show "Daria," which aired from 1997 to 2001, is among the bunch.

Out of 10 participants, only one correctly identified the angsty "Daria" theme. You'd think the signature "la la LA la la" opening notes would've tipped them off, but no. Six of the kids had never even heard of the show to begin with. ?

"I don't know what this is, but it sounds pretty badass," Morgan says while listening to the song.

"I've seen like screenshots of it and stuff on Tumblr, but I've never watched it," Tori said. Watch the full video below and get ready to feel old AF.
