For this activity we had the girls cut out a bunch of hearts. We also had pre-made cookies ready. The girls chose three ladies from the ward that they wanted to "heart attack". Since we live and Utah and we are close... we walked around to each of the doors, leaving tons of hearts on the door and the plate of cookies and a note from the girls. We door-bell ditched and the girls hid around while we watched the ladies open the door to thier surprise. The girls LOVED this activity.
