Watch it

“Modern Family” (9 p.m., ABC). Phil’s father (Fred Willard) comes to visit and Claire is less than thrilled.

“Cougar Town” (9:30 p.m., ABC). Travis has to choose between a college in California and one close to home. Oh come on, he’s not going to leave the cast after just one season.

“In Plain Sight” (10 p.m., USA). Mary takes an interest in a new witness’ love life.

“Late Show with David Letterman” (11:35 p.m., CBS). Robert Downey Jr. and OK Go. What’s not to like?

Record it

“Top Chef Masters” (10 p.m., Bravo). Five more chefs who I’ve never heard of try to impress the cast and crew of “Modern Family.”

“South Park” (10 p.m., Comedy Central). Jimmy and Timmy go to summer camp. But the real reason to tune in will be to see if the creators insert a reaction to Comedy Central’s censorship of last week’s episode.

“House Hunters International” (10:30 p.m., HGTV). A couple looks for a home in Slovenia. That could be super cool; I’ve heard Slovenia is one of the last “undiscovered gems” for travelers in Europe.

Got a comfy chair?

“Great Performances” (8 p.m., PBS). It’s a three-and-a-half-hour “Hamlet” for sci-fi geeks, starring “Star Trek: The Next Generation’s” Patrick Stewart and “Doctor Who’s” David Tennant. Oh, what’s that? They’re both famous Shakespearean stage actors? Yeah, riiiight.

Skip it

“Sunset Daze” (7 and 7:30 p.m., We). Wow, I still can’t believe this is for real: It’s being billed as a “Jersey Shore” for senior citizens, following a group of saucy, sex-obsessed residents at an Arizona retirement community. It sounds horrific. (In a brilliant bit of programming, the re-airings at 8 and 8:30 will be followed by an hour of “Golden Girls.”)

“Happy Town” (10 p.m., ABC). Series premiere. They’re trying to sell this eerie mystery/thriller as a modern-day “Twin Peaks,” but it’s getting awful buzz (here’s the L.A. Times and USA Today reviews) and, generally speaking, network series that debut this late in the season aren’t very good. Think of it as a bigger budget “Harper’s Island.”
