House, 8 p.m., Fox: You know a TV show is going downhill when they resort to characters with amnesia. We'd offer other storylines we came up with, but we forgot them.
24, 9 p.m., Fox: This show, if you'll remember, featured Jack's wife getting amnesia in the very first season. How's that for a record?
Glee, 9 p.m., Fox: Lea Michele's Rachel has laryngitis. Maybe she got it from announcing the Tonys with Jeff Daniels a few days ago.
V, 10 p.m., ABC: Erica searches for a scientist who has made a weapon the Visitors fear. Can we just call it red dust now, or do we have to wait until Michael Ironside shows up?
SEASON FINALE America's Next Top Model, 8 p.m., CW: Can we call it a surprise double elimination if we already know about it? Thankfully, they wait until there are only two finalists to shoot the inevitable commercial.
Top Chef Masters, 10 p.m., Bravo: The Simpsons' creator Matt Groening, voice actor Hank Azaria and writer Matt Selman judge a quick-fire challenge based on the show's characters. We can't wait to see what they come up with for Moe Syzlak.
Happy Town: The title of this episode is "Polly Wants a Crack at Her," which is so clever we forgot to check what the show is actually about. Oh, right, murders and such.
SEASON FINALE Supernatural, 9 p.m., CW: Let's start the apocalypse by killing off a recurring character, shall we?
SEASON FINALE Fringe, 9 p.m., Fox: This is only the first part of a two-part finale, but it does involve a parallel universe and Leonard Nimoy, so it's worth two mentions.
SEASON FINALE Smallville, 8 p.m., CW: Clark and Zod battle for control of the Earth. Will Callum Blue get to utter the immortal line, "Kneel before Zod!"?
Kitchen Nightmares, 9 p.m., Fox: A sushi restaurant owner loses his passion for cooking after one of his locations isn't successful. To be fair, is there a lot of actual "cooking" involved in sushi?
SEASON PREMIERE Gavin and Stacey, 9 p.m., BBC America: The couple have to adjust to living in Wales again. It's said the Welsh can be none too inviting to outsiders. Of course, those are English who say that.
