Time to get your GREEN on so you don't get pinched. I've no idea where THAT came from, but St Patrick's day, celebrated around the world, is the anniversary of the death of St. Patrick in the fifth century. The Irish have held this celebration for over 1,000 years, featuring Irish bacon and cabbage. I've never heard corned beef called Irish bacon before.
It says St Patrick was kidnapped at 16 and taken to Ireland as a slave. He later escaped and was credited with bringing Christianity to Ireland. In case you were wondering about the shamrock or clover as I know it, he used it to explain Father, Son and Holy Spirit. I never knew that before.
