(S04E07) After taking a week off for the William Shatner Roast, Reno 911! returns for the season finale, and we finally get to find out who it was that murdered Sheriff Chechekevitch with peanuts.

While the gang tries to figure out who did it, they also have to attend to the usually police business, which includes confronting a man at a carnival with a stage built into the front of his pants that hides what he refers to as an albino snake that "grows rigid in your grasp." Jones and Garcia can't see nor touch it though, because it's very sensitive to light and it's really more for women. The officers also answer a call from a pot dealer who's complaining about people trying to buy pot on a Sunday when he's closed. The officers threaten to arrest him for selling pot and the dealer threatens to arrest them for trespassing. When Garcia points out he can see the marijuana through the window, the dealer insists that's only ditch weed, and the good stuff is in the back with the cocaine.

(S04E04) After a pre-credit opening where the male deputies try to conduct a "panty raid" and end up face to face with a completely naked and pregnant Wiegel, we cut to the first real scene of the episode where a motivational speaker Dangle found on the internet gives the deputies some rather confounding advice, including this diatribe:

"I ask you, does the belt not go through all the loops? You all see yourselves as brilliant little pebbles just waiting for your code word. Well, what if your code word doesn't come, huh? Are you gonna sit around in your cruiser and wind up ejected from somebody's crazy physics package?"

More profound advice I've never heard. Let's move on.

(S04E02) Paul Rudd is a funny guy, and he should really do more comedy. He appeared in this episode, albeit briefly, as an instructor in Trudi's Lamaze class who informs the women, "your vagina will be ripped in half." That's about all we hear about Trudi and her pregnancy in this episode, though she does have a funny conversation with Williams where Williams explains to her that a baby must be fed everyday and cannot, as Trudi assumes, just have food laid out for it like a cat. Trudi counters with, "If I knew you were going to judge me on my parenting skills I never would have introduced you to my unborn child."

Rewinding to the beginning of the episode, the deputies discuss new policies on when they can and cannot shoot at a person. One of the new rules is that they can only shoot after they've already been shot once. Trudi inexplicably asks if she can shoot people and chickens who come into her yard.
