Zac Efron: "I Broke My Hand on Dave Franco’s Balls"

Neighbors is ostensibly the tale of a rivalry between a family and a frat. In actuality, the film's about a whole lot of dude love. Zac Efron went on The Tonight Show to promote the film and it ended up devolving into a discussion of man-crushes peppered with f-bombs.

According to Efron, the Franco brothers "have balls of steel" and Seth Rogan, who's already gone on record saying that Efron's "the sexiest motherfucker alive," made Efron take his shirt of for no other reason than Rogan's own voyeuristic pleasure.
