The Celtic saints were a fun loving people with many prayers that expressed this. Here is one I love that I thought you may enjoy as I focus on laughter today.
My walk this day with God,
My walk this day with Christ,
My walk this day with Spirit.
The threefold all-kindly;
Ho! Ho! Ho! The Threefold all-kindly
My shielding this day from ill,
My shielding this night from harm
Ho! Ho! Both my soul and my body,
Be by Father, by Son, by Holy Spirit:
By Father, by Son, by Holy Spirit.
Be the Father shielding me,
Be the Son shielding me,
Be the Spirit shielding me,
As Three and as One:
Ho! Ho! Ho! As Three and as One.
