"Monk" (9 p.m., USA): Guest-star alert: Andy Richter drops in on "Monk" as the offbeat detective series returns with new episodes. Richter plays a seemingly amiable everyman who befriends Adrian. Oh, but he may be hiding a little secret. "Monk" launches in front of "Psych," which also returns with fresh episodes.
"Ms. Adventure" (9 p.m., Animal Planet): Comedian Rachel Reenstra believes it's a jungle out there, from quibbling siblings to the dating front. In this new series, she taps into the animal world for clues to human behaviors such as courtship and clique-building. Who knew that bison live in exclusive fraternities and sororities, socializing only for mating? Or that male penguins present females with a rock -- not the eight-karat, emerald-cut kind -- during courting? Reenstra also interviews people, then compares their take on a topic with animals' habits.
"Hyperdrive" (9 p.m., BBC America): British exporters take to outer space to spread the word about the Queen, tea and other English stuff in this new comedy.
