Dandr started out as DANDYS = Dad and Young Sam, just 'cause it sounded nommish . . . Sam of DANDYS continues as YS, so I suppose I could be understood to have recruited, as well as sired and nommed him.
Source: email from Dandr.
In addition to what Dandr has said about me, Ys can also be the plural of the letter, which certainly sounds good to me, and was also the name of an old Atari video game. If pronounced 'ees', it can also be used to denote the poking of the neck. I will happily demonstrate at the next NPL get-together I attend.
