The Selkirk Grace is recited at a Robert Burns dinner, before dinner.

ha biadh aig cuid, 's gun aca càil,
acras aig cuid,'s gun aca biadh,
ach againne tha biadh is slàint',
moladh mar sin a bhith don Triath.

-- Robert Burns

If you can't read gaelic, here's a sane version of this poem:

Some hae meat and canna eat,
and some wad eat that want it,
but we hae meat and we can eat,
and sae the Lord be thankit.
-- Robert Burns
