My father told me this story recently about when he worked in an office building a few decades ago. Apparently, someone kept stealing the peanut butter & jelly sandwich out of his brown lunch bag in the fridge most days out of the week. After the first one, he labeled his bag, but it still kept happening. He said I was still in diapers at the time.
When he woke up after a full week of sandwiches missing, he decided to substitute what he found in my diaper that morning for the peanut butter that day, went into work and tossed his lunch into the fridge like normal.
At lunch, he went to check the fridge, and found the sandwich on top, with one big bite missing from the corner.
