UK, Ireland / Question about Irish-Polish similarities [25]

Hi all,

[ Intro ]
I'm a student from the US. My heritage is both Polish and Irish, and so for a project at my university, I thought it would be interesting to create a fictional restaurant/food shop, because the Irish and the Polish use a lot of the same ingredients for cooking (potatoes, cabbage, beef, etc.), that could help to bridge (in a small way) the divide between the two cultures in Ireland.

[I realize that there are not quite as many Polish people in Ireland now that the world economy has dropped, but I still thought it would make a great project].

[ Question ]
Anyways-- I was wondering what things in both cultures are really similar? These could be proverbs, jokes, drinking toasts, slang words etc.

Or even if someone could direct me to any websites that, like this one, discuss the Polish view of the Irish, or the Irish view of the Polish.

Any help would be greatly appreciated!
Thanks / Dziękuję bardzo
