Yatai no onêsan: Tabegoro na monojiri(2009)

Yatai no onêsan: Tabegoro na monojiri is a Japanese comedy following two lecherous brothers, Kinkichi and Senkichi, who operate a modest street-side izakaya. Perpetually unlucky in romance, they spend their evenings spying on a woman undressing in a nearby apartment—only to have the curtain frustratingly close before they see anything worthwhile. Their voyeuristic routine takes a comedic turn when their childhood friend Todoroki appears, revealing that the woman they've been watching is actually his girlfriend, Natsumi. The film mines humor from the brothers' misadventures and the awkward collision of their secret obsession with reality, blending slapstick and adult comedy in the style of vintage Japanese exploitation cinema.
