Our fáda, who art in Irish, annoying be thy name! (Old Irish Prayer about accented vowels.)

I also got a book called "500 Mallatacth Ort." It's a collection of curses in Irish and English and boy are there some doozies! "May you be stricken with diarrhea and a bout of sneezing at the same time!" "The devil eat you and spit you out because of the taste!" "Your waste lay crosswise inside you!" "Exorbitant rent to you!" "Crusts and scabs to your crotch!" One I heard years ago: "May the grass grow long before your door" -- and it's pretty bad when you think about it.
