One of Anita's sons has difficulty opening the box of his mom's ashes so the ashes can be spread. The other two sons try taking the box. With all three fighting over the box it rips open. This causes a large, noticeable ash cloud. Followed by two of the sons getting ash in their hair, on their face, one gets ash in their eye and all three sons are shown with gray ash on their clothing for the rest of the scene. Their sister standing nearby doesn't get any ash on her. All four of them are shown taking turns pouring out their mom's ashes in front of what they're sure is their grandpa's grave.
Most of the humor is dry or mildly sarcastic with some mildly "dark" or morbid jokes about death and dying.
