(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.

(S04E03) Typically, an episode of Reno 911! will have some semblance of a plot, but the bulk of the episode will be random scenes involving the officers. This particular episode actually stuck with its main plot of the officers discovering a jet ski once owned by a deceased officer, and only veered from that plot a couple of times.

One of the best "extra" scenes involved Trudi going to Lamaze class, once again with Paul Rudd playing the instructor. The two become rather cozy in front of the class, with Rudd's character showing Trudi the proper way to massage her breasts to get them to produce milk, and ending with her bent over and him behind her for some inexplicable reason. I'm not positive, but I think right before the scene changes you can see Rudd actually starting to crack up. That's actually one of many great things about this show being completely improvised; if you watch closely there are a lot of scenes where someone begins to lose it. Pay close attention to Tom Lennon whenever they do their PSAs, because he's almost always on the verge of completely cracking up.
