Well you can try to use it to get out of jury duty but that might backfire. It's generally not advisable to piss off a judge.

The real gangsta move is to get on a jury and use your knowledge and charisma to sway the rest of the jurors into delivering a just ruling instead of a compliant ruling.

But that's a once in a lifetime opportunity. It's like learning CPR. Best case scenario you never need to use it but in a less ideal scenario it could save a life.
