one day 25 or so years ago and asked him how he came up with the name. He told me that just as the first one came out of the mold his grand daughter said to his wife, who at the time was sitting on a stool watching, "Gee, grand ma, you have fatty knees". He thought it sounded like a good name so the rest is history. I had a lot of fun with mine but had to sell it when I went cruising. Sorry for your loss.
