I made a cake for work, and accidently swapped sugar for salt. As I was prepping it in the staff lounge, I cut myself a small bite, and tasted it, it was horrible! People were already arriving for lunch, and being known as someone who bake amazing cakes, people were excited to have a slice. Not knowing what to do, I picked up the cake, and using all of my acting abilities. "Stumbled" and dropped it on the floor.. Leaving a huge cake mess, but saving my reputation!
Best part was, that the boss felt so bad for me (and perhaps disappointed at not getting any cake) that he told me to head down to the local bakery and pick up a cake, and he'd wire me the money, to cover the expense!
