Agreed. And don't forget to listen to the warnings MySQL sends back,
e.g.:
mysql> create table temp_date(d date default null);
Query OK, 0 rows affected (0.15 sec)
mysql> insert into temp_date(d) values('2009-13-99');
Query OK, 1 row affected, 1 warning (0.00 sec)
mysql> show warnings;
+---------+------+----------------------------------------+
| Level | Code | Message |
+---------+------+----------------------------------------+
| Warning | 1265 | Data truncated for column 'd' at row 1 |
+---------+------+----------------------------------------+
1 row in set (0.00 sec)
mysql> select * from temp_date;
+------------+
| d |
+------------+
| 0000-00-00 |
+------------+
1 row in set (0.01 sec)

That's silly, if the data you want to insert is considered to be
invalid,
reject it,
don't replace it with NULL.
