This is a bit of a Gaelic tongue twister

Na bac le mac an bhacaigh is ni bhacfaidh mac an bhacaigh leat.

Pronounced :
Naw bock leh mock an wockie iss knee bockie mock on vockie lath

Don't trouble trouble and trouble will not trouble you.

Bacach is literally the lame man or the beggar. Mac an bhacaigh is the beggar's son.

Sliocht sleachta ar shliocht bhur shleachta (basically may your family live for many generations) - don't try this one at home, at least not with drink taken.
