Celebrate Batman Day with SQL

Because today is Batman Day, it calls for a celebration of the SQL type:

SQL> select listagg (b)
  2        within group (order by null) ||' Batman'
  3    from (select 0f/0 b
  4        from dual
  5      connect by level <= 14
  6      );

LISTAGG(B)WITHINGROUP(ORDERBYNULL)||'BATMAN'
