Well, with a last name of O'Malley, I know I've got some Irish in me. But since my paternal grandfather was an orphan, I don't know how much.
And FWIW, I know what you mean about everyone claiming to have Irish roots on St Patrick's day, on the South Side of Chicago it's even more prevelant.
I think it's sad though how we've corrupted this Saint's day in this country; in Ireland is it not more of a solemn occasion? Here it seems everyone uses it as an excuse to drink. Hell, the college town I'm in even has an Unoffical St. Patrick's day the Friday before, since Spring break usually covers the day. They don't want to miss any of the revenue from all the drunk college students.
Me, I think I'm going to go throw my corned beef in now, then maybe go out with some friends tonight to a local bar that's going to have live Irish folk songs and $2.50 pints of Guiness. What is it about pub songs where ANYBODY can sing them it seems
