Everywhere Paddy goes, his day goes with him. He's a well-travelled fellow, is Paddy. Welsh-born, taken as a slave by Irish pirates, escaped and went back as a Christian missionary. Some guts, that's why they celebrate his day with gusto everywhere from S. Francisco to New York and Boston to here. There are enough Irish pubs in London to cater for Paddy's mates, and the big brewery and pub chains get in on the act as well. Try stopping Paddy celebrate, it's like standing in front of a steam roller!
