Watch Seth Rogen Get Slapped In The Face With A Sex Toy In New ‘Neighbors’ Red Band

Zac Efron does the slapping in the latest trailer for the May 9 comedy.

Have you ever sat in front of your computer with a vague sense of ennui, wondering what was missing? Something just out of reach, something you just couldn’t quite name.

We found it. It’s Zac Efron and Seth Rogen swordfighting with a pair of ridiculously long, ahem, simulated genitalia accessories in the newest red band trailer for “Neighbors.” Fulfillment and contentment, here you come.

It’s not all sex-toy-slapping fun and games in the trailer. There’s also a baby watching Rogen and his onscreen wife, Rose Byrne, having sex, a gaggle of frat boys doing terrible Al Pacino impressions and the most creative use of repurposed automobile airbags we’ve ever seen, among other gags.

“Neighbors,” due in theaters on May 9, chronicles the battle between a certified Nice Young Couple (Rogen and Byrne) and the rowdy band of frat boys that moves in across the street, especially their fearless, shirtless leader, played by Efron. Nicholas Stoller, who also brought us “Forgetting Sarah Marshall,” “Get Him To The Greek” and “The Five Year Engagement,” directed the flick, so prepare to have your funny bone aggressively tickled.

Can’t get enough of the feud? Check back in with MTV News later this week, when “Neighbors” takes over ahead of the 2014 MTV Movie Awards.
