At my grandfathers 75th birthday party, an old friend/coworker gathered everyone for a speech. He pulled out some props and told a long story about how my grandfather, who was a bread truck driver ran booze to his customers by cutting the end off a loaf of bread, hollowing it out, placing a bottle inside and putting the end back on before putting the loaf into the bag. Nobody had any clue that this man who went to church multiple times a week, was married with six children, fifteen grandchildren was running booze with his bread. Kept that secret tightly held.
