An Italian, an Irishman and a Polish man, all first time 
fathers, are pacing nervously in a maternity ward waiting 
room when a nurse rushes out of the delivery room holding up
a new black newborn. "Yours?" she asked the Italian man, who 
immediately curses her out in Italian and says "No! notta 
my kid!"

"Yours?" The nurse asks the Irishman, who answers "It bloody 
well not be!" 

"OK, then it must be yours", she informs the Pole, who 
sheepishly looks at the ground and mumbles "It must be, my 
wife burns everything!"
