mysql and regular expressions
The first time I needed to have some kind of complex select statement, I started to pray about the ability to use regular expressions with mysql.

For example:
SELECT * FROM db.ip_addresses WHERE ip_address REGEXP '^192\.168\.0\.(133|135)$';
See the official documentation and details here.
