I learned this phrase on Sunday: Det spiller ingen rolle. It means "It plays no role", which is the expression for "It doesn't matter".
On Monday, I was searching Trondheim rentals, and one ad ended: "Gutt eller jente, det spiller ingen trille! ;-)". That means "Boys or girls, it plays no 'roll'" where 'trille' means 'roll' as in 'roll your r's'. So this is a joke that requires one to know that 'trille' is english for 'roll', which sounds like norwegian 'rolle'. A cross-language pun. Cool!
