Ever wonder what Zac Efron and Seth Rogen would look like as tween girls?

We didn't think so. Still, the Neighbors co-stars dressed in drag Tuesday as part of The Tonight Show's recurring "Ew!" sketch. TeenNick host Stacy Wallace (Jimmy Fallon) kicked her fictional TV show off by inviting her "bestie" Allison Donnelly (Rogen) to join her on the couch. What's she up to these days?

"My mom gave me her credit card so I stopped by Starbucks on the way here," Allison said.

"Ew!" Stacy replied. "What did you get?"

"A venti soy cinnamon dolce cream Frappuccino!" Allison said. Did she get whipped cream, too? "Ew!" she told Stacy. "Of course!"

Enter Brittany Anderson (Efron), the girls' other BFF. What's new with her? "I'm actually super excited right now because I just got this new phone and it has an amazing camera," she told her girlfriends. "It's got, I think, like, eight megapixels—so it's like perfect for selfies! I've been taking them all day!"

The trio took a series of snapshots before shifting the discussion to music. "There's this one song that I just cannot get out of my head," Brittany said. "It's called 'Turned Down for What.'"

"Oh my god, I love that song!" Allison said.

"Then let's stop talking about it and listen to it!" Stacy shouted before turning the Lil' Jon jam on.

Their twerk session was interrupted moments later. "Ew! It's my stepdad, Gary!" Stacy said. "He's so lame!" After some awkward banter with her stepfather (A.D. Miles), they did an "Ew!" lightning round.

Topics covered included Crocs, tomatoes, baby sloths, Gary Oldman and...James Franco?!
