Billie Eilish [1] is about to make her Saturday Night Live [2] debut as the musical guest on the season 45 premiere, but in order to do so, she needs a little help. In a promo clip shared Wednesday, the 17-year-old singer [3] gets the assistance she's looking for from none other than veteran host Woody Harrelson. There's just one problem: she wasn't alive for two out of his three SNL gigs.

"You should've been, you missed a lot of good years," Harrelson told her, before they took a tour of Studio 8H. Eilish is the "new kid" in the school of SNL, and she meets the stereotypical jocks (Colin Jost and Michael Che) and an overeager class president candidate (Heidi Gardner). Watch the full video above to see the hilarity ensue, and be sure to watch Harrelson and Eilish as they take over the show on Sept. 28.
