Complete Savages (2004)

Single father Nick Savage runs a 'macho' household, having five school-age sons, all rowdy slobs except sensitive, polite 'nerd' Sam, who nevertheless envies dating-slick athlete Shawn. That changes when distantly admired Angela becomes his steady date, a base nine of his brothers ever reached or would admit wanting. Nick's younger brother and fire department colleague Jimmy is their welcome regular guest, but frankly serves as bad adult example of irresponsibility.
