foreign key constraint to itself

Hi, I am just wondering can I create foreign key constraint to itself in mySQL innodb (the mySQL 3.23.50 release)? Let's say we have a table: test_table_01 (id integer, pid integer) type = innodb. Can I create a foreign key on pid and reference to test_table_01 (id)? Thanks,
