Seth Rogen is not a good looking woman. Zac Efron, on the other hand, kind of seemed like a natural.

Appearing on the Tonight Show to promote their new movie Neighbors, the two actors joined host Jimmy Fallon for a recurring sketch Fallon calls “Ew!” Efron actually showed up a day early, as Rogen was last night’s guest and Efron is scheduled to take his turn tonight.

"Ew!" is actually pretty funny, and (likely on purpose) feels like a classic Fallon Saturday Night Live sketch. You have to love how into it Rogen and Efron get, and how weird the step-dad Gary is. 

Also, if you can figure out what is going on with Fallon’s accent, we’d be very impressed.
