Two more old Yiddish curses (in memory of my late friend, Elmar Lanczos, who told me of these):
Person with bad stammer, "Wh-wh-when I d-d-die, I w-w-w-will be-be-bequeath y-y-you my m-m-m-m-mouth!"
And
May you have a hundred mansions. And in each mansion, may you have a hundred bedrooms. And may each bedroom may you have a hundred beds. And may insomnia keep you bouncing from bed to bed!
