The child heroes from Netflix's megahit series goofed around with host Jimmy Fallon on Wednesday and it was immediately apparently why America has fallen in love with the show, and with its adolescent stars.
Millie Bobby Brown, who plays Eleven, Finn Wolfhard, who plays Mike Wheeler, Gaten Matarazzo, who plays Dustin Henderson, and Caleb McLaughlin, who plays Lucas Sinclair, sat down with Fallon for an interview and a brand-new game called "Stranger Strings."
[Spoiler Alert: If you haven't watched Stranger Things, the sketch has some major spoilers. Also, why are you reading this? Watch it. Now.]
The cautious redhead -- played by Tonight Show head writer A.D. Miles, not the lovely Shannon Purser -- made her way back from the Upside Down and into the basement where Mike, Lucas, Dustin and Eleven are all playing Dungeons and Dragons, confronting the kids about why she was left "laying in a cocoon with a f**king slug" coming out of her mouth.
"Let's review, shall we? There were two people down, there, and you rescued one of them," Barb yells, flipping off the kids. "Do the math, a**holes!"
"I guess no one could find you, it was pretty dark down there," Lucas suggested.
"Yeah, yeah, good point. I don't have a very distinctive look!" Barb sniped back. "I don't have bright red Ronald McDonald hair, old granny glasses and a librarian's blouse!!"
"Nobody even cares that I was missing!" she continued, screaming at an even higher pitch. "No search party for Barb! No fake corpse stuffed with cotton for Barb!!"
So how did Barb escape from the otherworldly hellscape? It turns out she made a deal with the Demogorgon: her life for Will's, meaning the kid who was missing for the entire first season is back in the Upside Down, while Barb is getting her own Netflix show: Orange Is the New Bitch.
After the sketch, Brown, Wolfhard, Matarazzo and McLaughlin sat down with Fallon for a hilariously adorable interview about the show, where the kids opened up about Brown and Wolfhard's awkward kissing scene, which was her very first kiss ever.
"Finn went through two packets of Tic Tacs," said the 12-year-old actress.
"Yeah, it was awesome," Wolfhard added enthusiastically.
"Yeah, you didn't have to do that many takes," Fallon laughed, poking fun at the 13-year-old star.
Apparently, the cast didn't make things much easier on set. During the kissing scenes, McLaughlin and Matarazzo gawked at them from the sidelines while the show's directors, Matt and Ross Duffer, tried to make them laugh during the takes and sent them kissing emojis to make them blush.
After their adorable interview, Fallon and the four young stars sat down for a new Tonight Show game called "Stranger Strings." Each star wrote down a secret before the show, then those secrets were read aloud and everybody sprayed Silly String in the face of whomever they thought wrote that secret.
While it was hilarious to watch all the kids basically use it as an opportunity to spray Fallon in the face, Brown also showed off her rap skills with a surprisingly epic rendition of Nicki Minaj's verse from "Monster."
