I'm looking at a commit message from one of my clients today, which is just "Not, new bins, cant stop bins" and a check-in of several hundred dlls generated as build artifacts. Six days later another developer at the client checked-in a commit that removed all of the dlls, with the message "remove BIN folder".

Some other examples: "Fixes to make work", "Left Over", and their most common message " ".

They're nice guys to work with, but their VC habits are awful.
