GRANDMA AND GRANDPA WERE VISTING THEIR KIDS OVERNIGHT,WHEN GRANDPA FOUND A BOTTLE OF VIAGRA IN THE MEDICINE CABINET. HE ASKED ABOUT USING ONE OF THE PILLS. THE SON SAID, I DON'T THINK YOU SHOULD TAKE ONE DAD. THEY'RE VERY STRONG AND VERY EXPENSIVE. HOW MUCH? ASKED GRANDPA. $10.00 A PILL, ANSWERED THE SON. I DON'T CARE,SAID GRANDPA, I'D STILL LIKE TO TRY ONE,AND BEFORE WE LEAVE IN THE MORNING, I'LL PUT THE MONEY UNDER THE PILLOW. LATER THE NEXT MORNING, THE SON FOUND $110 UNDER THE PILLOW. HE CALLED GRANDPA AND SAID ,I TOLD YOU EACH PILL WAS $10 NOT $110. I KNOW, SAID GRANDPA. THE HUNDRED IS FROM GRANDMA!.....
