Coming back from commercial, we now get the completely-unnecessary-except-for-morons-I-suppose "HARVARD UNIVERSITY" giant floating letters. Olivia tells Walter she's ordered a "standard forensics work package" and asks if there's anything else he needs, and he rattles off a laundry list of sciencey stuff, leaving Farnsworth scrambling for a damn piece of paper. Among the items he needs: a cow, with specific breeding, weight and body fat. Olivia's all, whuh? Peter explains that, genetically speaking, cows and humans are separated by only a couple of strands of DNA. My own empirical evidence from a recent trip to the amusement park suggests he's being generous. Anyway, that makes cows an ethical test subject somehow. Perhaps "acceptable substitute for humans, scientifically speaking" maybe, but I know many people who would take issue with Peter's "ethical" comment. Olivia snidely asks him if he learned that at MIT, and Peter weirdly says, "No, from reading books. You should try it sometime." I'm not sure I get the Olivia-is-anti-book crack. Maybe it's a plain ol' "you're stupid" crack. Given how Olivia stares at him for half an hour before telling Farnsworth to get Walter a cow, maybe he's onto something. Walter gleefully says the only thing better than a cow is a person. Unless you need milk, in which case you need a cow, he adds. He does know that humans produce milk too, right? I mean, he's a scientist. He's crazy, not stupid.

Then we get the "scientist at work" montage, with Walter making notes and looking at slides, and then there's some farmer bringing in a cow and instead of, oh, I don't know, bringing it in the rear entrance or wherever it was that all this massive equipment in the lab came in to the building, he naturally leads it right down a crammed hallway full of students, like thanks for bringing your big dirty manure-dropping powerfully kicking bovine right down the hallway, Farmer Bob.

Olivia chews her fingernails and reads something (probably looking for a replacement QB for her fantasy football team after Brady went down). Peter brings her some coffee and asks her what else is in her super-secret file that she has on him, and she says she's not at liberty to say. He thinks he deserves a little more info after all he's done, and she finally admits that there is no file. He can't believe she was bluffing. "I'm really good at reading people; that's sort of what I do," he says. He laments that he could have stayed in Iraq. Olivia points out that a car bomb went off in Kirkuk this morning, so he probably owes her a thank-you. Peter laughs. "Yeah, well, I owe a lot." Olivia guesses the Mafia, and Peter admits he owes a lot of money to a guy named Big Eddie and the two of them have a heartwarming conversation about how Peter had a great system to beat the casino but the house cheated, and maybe the two of them could think about doing something useful instead of flirting with each other.
