Only Law Firm in Town

"When you have only one lawyer in town, he's usually barely making a living and is just hanging on. Once you have two law firms in town, we discover that both lawyers are now quite prosperous members of the community."

- Typical lawyer joke

The law firm at the center of the show. You'd think occasionally, the plaintiff in one of these cases would pick a different firm. Instead it seems like there's only one law firm they can possibly go to.

A sister trope to Only Shop in Town.
