We children of the diaspora can enjoy a good joke, even one that targets us. We grow up with an acute awareness that we are the viewed by many as the "lazy Irish," the "drunk Irish," the "pugnacious Irish," the "superstitious Irish," etc. We also enjoy the fact that everyone wants to Irish on the venerated Saint's day.
So, take your humor where you find it, there is much too little of it in this world today.
