You know how you've won a case against a contractor who did a crappy job?
When your adversary calls you to tell you that his client not did not nothing wrong but will have an experts report showing just how perfect the job was so the complaint should be dismissed. You tell your adversary, ah no, but feel free to get your report because I already have mine. And your adversary tells you well, I don't know who you used but we have the most repsected guy in the industry who will support our side of these events. And you tell your advery well have at it.
And you come to find out that the perfect expert that your adversary thinks he has.... is actually the one you already have. So you let your adversary know this. Adversary is, of course, speechless.
