Other side of the coin
I resigned from one job, on a 3 month notice period. They found a replacement within a month, and the usual "handover" discussion started. . Instead, I said to my boss "It's really not fair on the new guy if I'm hanging around al the time; it'll cramp his style terribly. How about I, you, know, not show up?" They fell for it and I had a couple of months of rather well paid garden tending, and my boss thought I was being rather kind.
