Doctor and a nurse having an affair

A doctor was having an affair with his nurse.Shortly afterward,she told 
him she was pregnant.Not wanting his wife to know,he gave the nurse a 
sum of money and asked her to go to Italy and have the baby there."but 
how will I let you know the baby is born?"she asked.He replied,"Just 
send me a post card and write "spagetti"on the back.I"ll "take care of 
exspenses" Not knowing what else to do,the nurse took the money and flew 
to Italy. 

Six months went by and then one day the doctor's wife called him at the 
office and explained,"Dear you recieved a very strange postcard in the 
mail today from Europe,and I don't understand what it means."The doctor 
said,"Just wait till I get home and I will explain it to you." 

Later that evening,the docotor came home,read the postcard,fell to the 
floor with a heart attack. Paramedics rushed him to the ER.The lead medic 
stayed back to comfort the wife. 

He asked what trauma had precipitated the cardiac arrest.So the wife picked 
up the card and read,"Spaghetti,Spaghetti,Spaghetti,Spaghetti-Two with 
sausage and meatballs, and two without."
