In the spirit of the legend of St. Patrick's use of the shamrock to teach the Trinity, here are three videos to help celebrate the day:
May the road rise up to meet you.
May the wind be always at your back.
May the sun shine warm upon your face;
the rains fall soft upon your fields and until we meet again,
may God hold you in the palm of His hand.
And if you plan to partake today, don't kid yourself that you'll only go for The One.
