Timothy Olyphant must be having a blast playing himself, as the rival and successor to Rob Lowe’s “Grinder” on this comedy series – because he’s back yet again. And this time, he’s irritating Lowe’s Dean by engaging in a mock trial with him. Dean’s already making a mockery of the law by practicing without a law degree or passing the bar, but now there are two unqualified “attorneys” doing battle. And that makes this, of course, a mock mockery.
