  You can see instances of this when a team's batsmen 
  are destroying a sub-standard  bowling  attack and want 
  to give others a turn and leave the field after they'd had a 
  decent bat.

  On a related note, Abdul Aziz of Pakistan has the
  unfortunate distinction of being the only player to
  be recorded as 'retired dead'.
