In my job we had a guy that we would joke was the cause of all our issues (he obviously wasn't and knew this, as we used to say it about things he hadn't even touched). He eventually left for to wanting a more stable job before getting a mortgage arrive we were on the way to going under (still fighting that to this day). Even though he's gone we still use him as reference to be like "I fixed what X broke". Sort of used now as a way to not actually blame anyone in the company for things. Things go wrong and we fix them, no point in actually blaming anyone.
