A few years ago I added a featuregg to the site I worked on at the time, where it would reject correcthorsebatterystaple as a password with an error message acknowledging their impeccable taste and a link to a relevant xkcd. At some point they made a number and a special character a requirement in the password and the code was either stripped (or still sat there and never triggered). The irony isn't entirely lost on me.
