Fallon reprised his Sarah character and her talk show "Ew!" last night, and Efron and Rogen were her special guests for the episode. Rogen played a bearded girl named Allison and Efron played selfie maestro Britney.
After taking a few photos, the girls decide to get down to Lil' Jon's "Turn Down For What," before Sara's stepfather interrupts them and starts singing about granola.
Following a "speed run" that revealed Allison's affection for Gary Oldman, the girls mention their disgust for Rogen's pal James Franco – then poke fun at his recent scandal involving texts to a teenage girl. Ouch!
Efron gave a sneak peek on Instagram as the show started, writing, "@jimmyfallon is S-A-R-A with no H, because H’s are#Ew! Don't miss #ZacEfron on #FallonTonight!"
