MySQL running out of date

[Hans van Harten]

Some make the laughing stock of MySQL with this code:
    create database data_test ;
    use data_test;
    create table test3 (a date);
    insert into test3 values (-1);
    insert into test3 values ('1996-02-31');
    insert into test3 values ('1996-67-31');
    select * from test3;

I ran it on MYSQL-4.10-max and was not amused.
Anyone to comment??
