I didn't change anything!

( interj.)

   An  aggrieved  cry  often  heard as bugs manifest during a regression
   test.  The {canonical} reply to this assertion is "Then it works just
   the same as it did before, doesn't it?" See also {one-line fix}. This
   is  also  heard  from  applications  programmers  trying  to blame an
   obvious applications problem on an unrelated systems software change,
   for  example  a  divide-by-0  fault  after  terminals were added to a
   network.  Usually,  their  statement is found to be false. Upon close
   questioning,  they will admit some major restructuring of the program
   that  shouldn't  have  broken  anything,  in their opinion, but which
   actually {hosed} the code completely.
