The developer's mantra

I'd like you to take the time to learn the developer's mantra:

The Tester is always right. I will listen to the Tester. I will not ignore the Tester's bug reports. The Tester is god. And, if this ever happens again, the Tester will personally rip your lungs out.

This comes courtesy of Abi, who subverted the Babylon 5 mantra for the purposes of educating inexperienced developers.
