I started noticing eggs vanishing from our fridge, always after my mother-in-law Andrea visited. At first, I thought she might be struggling and taking a few to get by—but the disappearances were too consistent to ignore. So, I set up a hidden camera. What I saw stunned me: Andrea was stealing our eggs, carefully wrapping them, then walking across the yard to sell them to our neighbor, Mrs. Davis—claiming they were from her non-existent backyard chickens. Furious but clever, I devised the perfect payback. I hollowed out, a carton of eggs and refilled them with a nasty mustard-hot sauce mix. Sure enough, Andrea took the bait and sold the sabotaged eggs to Mrs. Davis. Later that day, Mrs. Davis cracked one open and shrieked. She stormed over, hands covered in mustard, demanding answers. I let her—and Andrea—know exactly what had happened. Andrea was humiliated, Mrs. Davis was furious, and my fridge has been egg-theft free ever since. Sometimes, revenge is best served spicy… in an eggshell.
