A leprechaun is an Irish fairy who looks like a small, old man about 2 feet tall. He is often dressed like a shoemaker, with a crooked hat and a leather apron.
One traditional symbol of Saint Patrick's Day is the Shamrock.
"Shamrock" is the common name for several different kinds of three-leafed clovers native to Ireland.
It is named after Saint Patrick (AD 387–461), the most commonly recognised of the patron saints of Ireland.
What I liked was that the Guinness factory has a contract for 9000 years
