I made cereal box headstones and tried to think of clever sayings that went with the particular type of cereal.
I used "Snap, Crackle, POP!" for Rice Krispies, and "Sorry, Mikey" for Life and so on. For the headstones, I opened the boxes and glued them inside out. I used a black marker to add a date and the epitaphs. For others, I created wounds with red paint and black marker. I even used a large plastic dagger in one.
Here are a couple additional photos.
