buried treasure

( n.)

   A  surprising  piece of code found in some program. While usually not
   wrong,  it tends to vary from {crufty} to {bletcherous}, and has lain
   undiscovered  only  because  it  was  functionally  correct,  however
   horrible it is. Used sarcastically, because what is found is anything
   but  treasure.  Buried  treasure almost always needs to be dug up and
   removed.  "I  just  found  that  the  scheduler sorts its queue using
   {bubble sort}! Buried treasure!"
