Funny story... when I was in 8th grade, my friend and I noticed a few colorful, plastic eggs poking out from under my fence. Peeking over the fence, we realized that some proactive neighbors were setting up for an easter egg hunt. Well, as adolescents with nothing to do, we thought it would be funny to take out the candy and chocolate found inside the eggs, and replace it with whatever we could find around the house. In the end, we filled half a dozen eggs with either dog poo, vegetable oil, chocolate syrup, or salt.
A few hours later, to our surprise, we had an angry mother in a pink bunny suit banging on our backdoor, yelling at my brother about trying to poison the neighborhood children. One of the less rational periods of my life, but a funny story, nonetheless.
