I love to cook with wine.      Sometimes I even put it in the food.

Years back the company accountant poked his head into the R&D lunchroom, and announced he knew a maths trick we didnt - namely that when adding a string of numbers up, if you get 2 different answers and the difference between the two is divisible by 9, then you have transposed some digits.

So we spent the next 10 minutes analysing it, and came up with a general proof - for any arbitrary amount of transposition within each number, the resulting error is always an integer multiple of BASE-1. Not very helpful in Binary though.

We frightened the poor guy off.
