Zac Efron and Seth Rogen who are costarring in the upcoming movie "Neighbors" compete for a spot in the cubicle with the boys of Comedy Central's Workaholics. The stars try out to be the fourth member in the Adam, Anders and Blake cubicle. The full clip can be watched below!

Efron and Rogen do some very funny stuff in the video to win the fourth spot. Efron does a lap dance for Adam while Rogen shakes his head at his shameless costar. "Daddy likes," Adam Devine says in the clip. "Come on, let me get a turn!" Anders exclaims. "Dude, dance on my lap." Rogen says, "I'll dance on your lap," but Anders doesn't want him, he wants Efron. Efron sits down after his dance and Adam says, "We have some weird vibes, I like that about us." Zac later drops his trousers for the group and shows all the guys his private parts. That's when Seth exclaims: "It's amazing, it's beautiful!" Then Rogen hilariously says, "Your balls have a six pack."

Rogen and Efron are promoting their new movie, "Neighbors." Seth Rogen and Rose Byrne play a couple with a newborn baby who move into a new neighborhood and face unexpected difficulties following the establishment of a fraternity house in the adjacent residence in the comedy "Neighbors." An intensive conflict between the couple and Zac Efron's character's fraternity ensues. "Neighbors" is directed by Nick Stoller ("Forgetting Sarah Marshall," "Get Him to the Greek") and written by Andrew Cohen and Brendan O'Brien. The movie will hit theaters on May 9, 2014.
