Marriageable Lads (1963)

Fotis and Kosmas, two inseparable friends and business partners, think it's high time they walked down the aisle with their long-term sweethearts. However, there's a tiny detail standing in the way of happiness: the two companions must first marry their younger sisters Dora and Thalia off to suitable bachelors before they start planning their wedding. And as if that weren't enough, Kosmas and Fotis are unaware that they have fallen in love with each other's sister. Is there any way to get out of this fine mess before it's too late?
