When faced with a client who wants to go to trial 'on prinicple' who hasn't used the Chewbacca Defence?

The Chewbacca defense is a fictional legal strategy used in episode 27 of South Park, "Chef Aid", which premiered on October 7, 1998, as the fourteenth episode of the second season. The aim of the argument is to deliberately confuse the jury by making use of the fallacy known as ignoratio elenchi or red herring: It starts by stating that Chewbacca lives on Endor and continues by unwinding a series of nonsense conclusions. The concept satirized attorney Johnnie Cochran's closing argument defending O. J. Simpson in his murder trial

Cochran



...ladies and gentlemen of this supposed jury, I have one final thing I want you to consider. Ladies and gentlemen, this is Chewbacca. Chewbacca is a Wookiee from the planet Kashyyyk. But Chewbacca lives on the planet Endor. Now think about it; that does not make sense!


Gerald Broflovski


Damn it!... He's using the Chewbacca defense!


Cochran


Why would a Wookiee, an eight-foot tall Wookiee, want to live on Endor, with a bunch of two-foot tall Ewoks? That does not make sense! But more important, you have to ask yourself: What does this have to do with this case? Nothing. Ladies and gentlemen, it has nothing to do with this case! It does not make sense! Look at me. I'm a lawyer defending a major record company, and I'm talkin' about Chewbacca! Does that make sense? Ladies and gentlemen, I am not making any sense! None of this makes sense! And so you have to remember, when you're in that jury room deliberatin' and conjugatin' the Emancipation Proclamation, does it make sense? No! Ladies and gentlemen of this supposed jury, it does not make sense! If Chewbacca lives on Endor, you must acquit! The defense rests.
