Character mistake: In arguing Alan Shore should be fired, Paul Lewiston says he conducts himself disreputably at every firm he's worked for, and that his last firm sued him. This would seem to be a reference to the final season of "The Practice." However, it was Alan who was the one to sue Young, Frutt and Berluti, claiming wrongful termination. In fact, the reason Alan is even associated with Crane, Poole and Schmidt to begin with is because they're the firm he hired to sue YFB, leading to Denny offering him a job.

Alan Shore: Ah, Denny, I've hardly seen you this episode.
Trivia: The footage of Denny Crane as a young man trying a case with his father comes from a TV play called "The Defender", broadcast live in 1957. The details of the case and trial are the same as referenced in this episode, and the title of this episode is a direct reference. One notable difference is that Joseph Gordon, here played by James Keane, was played by Steve McQueen in the original, who of course couldn't reprise his role.
