I Now Pronounce You Chuck & Larry 2007

They're as straight as can be, but don't tell anyone.

Directed by Dennis Dugan

Firefighters Chuck Ford and Larry Valentine are guy's guys, loyal to the core—which is why when widower Larry asks Chuck to pose as his lover so that he can get domestic partner benefits for his kids, his buddy agrees. However, things get dicey when a bureaucrat comes calling, and the boys are forced to present a picture of domestic bliss.
