I have learnt quite a few Polish words in the year that I've been with my girlfriend, but have always struggled to build them into sentences (owing to the extremely difficult grammar involved)...
..I did manage this one recently though...
Jestem żielony, dlatego jestem żabko
(Yeah yeah, I maybe 33 years old now, but in my defence, my surname IS Green, and some say I do look a bit like a frog (-I don't.. I definately look English!)
So, along this colour theme, are there any other phrases like this that I could use to make her laugh at me???
