Zac Efron and Dave Franco stole the show when they took the stage during the 2015 MTV Movie Awards. The pair, who were accepting the award for Best Duo, re-enacted a scene from their hit comedy "Neighbors."

Like the movie, the actors hit the stage dressed as different Robert de Niro characters. Fans of "Neighbors" will remember that much to the dismay of their neighbors (Rose Byrne and Seth Rogen), Franco and Efron's fraternity throws a de Niro themed party in which the brothers dress as different characters the esteemed actor has played. In the film and at the awards Franco opted to dress as de Niro's character in "Meet The Fockers," while Efron took on his "Taxi Driver" character, sporting a green bomber jacket and a mohawk wig. On stage the pair brought the laughs as Efron tried, and failed, to take things in a serious direction with his acceptance speech. Franco interrupted multiple times, attempting to milk his shirtless co-star on stage, paying further homage to de Niro's "Fockers" role. Efron later got payback in an NSFW move when he re-enacted the scene where he grabs hold of Franco's crotch.

Efron and Franco beat out Channing Tatum and Jonah Hill in "22 Jump Street," Shailene Woodley and Ansel Elgort in "The Fault in our Stars," Bradley Cooper and Vin Diesel in "Guardians of the Galaxy," and James Franco and Seth Rogen in "The Interview."
