One of the best episodes, when Robert Blake pleads with the Judge for his mentally challenged friends release, is absolutely brilliant performance, raw and real.
Baretta: (to Rooster) I'm the Rainmaker, nobody horns in on my territory.
Baretta: (to the Judge) But if you try to put him in a cage, he's gonna bang up against that cage, and bang up against it and gonna die your honor. That's what's gonna happen to Willie. You take him away from us, and you're gonna kill him, and if he dies, we are all gonna die a little bit. Please save him your honor, please save all of us.
Baretta: (to Rooster) If you think you look like an Indian, well I'm Ryan O'Neal then.
Schiller: Where do you find the strength for all these cousins?!
Baretta: Ah, you should of seen this one.... I don't always have the strength sir, which is why I had to rest up a little, take a little nap this morning.
Baretta likens himself to the Burt Lancaster charismatic con man from The Rainmaker who breezes into a drought-stricken Western town claiming he can bring the rain. But he winds up transforming it and the local spinster as well.
