A Night at the Roxbury (1998)

Despite being well into adulthood, brothers Doug (Chris Kattan) and Steve Butabi (Will Ferrell) still live at home and work in the flower shop owned by their dad (Dan Hedaya). They exist only to hit on women at discos, though they're routinely unsuccessful until a chance run-in with Richard Grieco (Richard Grieco) gets them inside the swank Roxbury club. Mistaken for high rollers, they meet their dream women, Vivica (Gigi Rice) and Cambi (Elisa Donovan), and resolve to open a club of their own.
