Charles: Here it is. The original Boyle family sourdough starter, the mother of the mother dough. It's still good, but the lid on the jar has been stuck for over a hundred years.
Sam Boyle: There's an old family legend that it can only be opened by The One True Boyle.
Lyndon Boyle: I wanted to show my dad that I was not a disgrace to the family. But I couldn't budge it. Maybe he was right.
Jake: Oh, Lyndon. What a tale. But I don't think that's why you came in this barn at all. I think you came in here for this.
Sergeant Jeffords: Is that nutria poison?
Charles: It's rat poison. Nutria are pets. You psychopath.
Jake: Ah. Nitrobenzene. That causes the exact type of ulcers we found in Pappy Boyle's mouth. And look what we have here. A single brown hair, belonging to the murderer. Terry, please send this off to the local police station for a DNA test. Now all we need is one of your hairs, Lyndon.
Lyndon Boyle: I didn't kill my father. Why am I being singled out?
Sam Boyle: Why not take a hair from every Boyle so Cousin Lyndon doesn't feel that way?
Charles: Sure, great idea. I'll go first.
Jake: I mean it's more work for the lab, but it's fine with me. Are you okay with that, Lyndon? [Lyndon plucks a hair] Oh, wow. Went with a nose hair. Didn't see that coming. But it's definitely long enough.
Sergeant Jeffords: [chuckles] No.
