Greed is sure to bring about Ruin Story

Here's a story: In a store, a jar of jam accidentally broke. A bunch of flies showed up to eat the jam. They wouldn't leave until they ate it all, even though their feet got stuck in the sticky jam. Sadly, they couldn't fly away and ended up dying. As they died, the flies realized, "We were really foolish! We risked our lives just for a bit of jam."
