Nuns Drinking Beer

TWO NUNS WERE SHOPPING AT A 7-11  STORE.  AS THEY PASSED  BY THE BEER COOLER, ONE NUN SAID TO THE  OTHER, " WOULDN'T A NICE COOL  BEER OR TWO TASTE WONDERFUL ON A HOT  SUMMER EVENING?"            THE SECOND NUN ANSWERED,  "INDEED IT WOULD, SISTER, BUT I WOULD NOT FEEL COMFORTABLE BUYING BEER, SINCE I AM  CERTAIN IT WOULD CAUSE A SCENE AT THE CHECKOUT STAND."  "I CAN HANDLE THAT WITHOUT A  PROBLEM" THE OTHER NUN REPLIED, AND SHE  PICKED UP A SIX-PACK AND HEADED FOR THE  CHECK-OUT.                                                                         THE CASHIER HAD A SURPRISED LOOK ON HIS FACE WHEN THE TWO NUNS ARRIVED WITH A SIX-PACK OF BEER.  "WE  USE BEER FOR WASHING OUR HAIR" THE NUN SAID, "BACK AT OUR NUNNERY, WE CALL IT CATHOLIC SHAMPOO.                  WITHOUT BLINKING AN EYE, THE  CASHIER REACHED UNDER THE COUNTER. PULLED OUT A PACKAGE OF PRETZEL STICKS, AND  PLACED THEM IN THE BAG WITH THE BEER.  HE THEN LOOKED THE NUN STRAIGHT IN THE  EYE, SMILED, AND SAID:  "THE CURLERS ARE ON THE  HOUSE."
