noddy

noddy: /nod'ee/ adj.  [UK from the children's books]
   1. Small and un-useful, but demonstrating a point.  Noddy programs
   are often written by people learning a new language or system.  The
   archetypal noddy program is {hello, world}.  Noddy code may be
   used to demonstrate a feature or bug of a compiler.  May be used of
   real hardware or software to imply that it isn't worth using.
   "This editor's a bit noddy."  2. A program that is more or less
   instant to produce.  In this use, the term does not necessarily
   connote uselessness, but describes a {hack} sufficiently trivial
   that it can be written and debugged while carrying on (and during
   the space of) a normal conversation.  "I'll just throw together a
   noddy {awk} script to dump all the first fields."  In North
   America this might be called a {mickey mouse program}.  See
   {toy program}.
