It has now happened three weeks in a row: those taping "Glee" likely missed the last few minutes of the episode because "American Idol" is incapable of ending their show on time.

I know, I know. We can tape the show after "Glee" to make sure we catch everything, but we shouldn't have to do that. There are already way too many good shows on Tuesdays at 10 for me to give up taping one of them to make up for Fox's ineptitude.

So if you missed the ending last night (like me), you missed guest star Kristin Chenoweth performing the song, "Home."

You can watch it below.

Dancing with the Stars (8pm, ABC) -  Melissa Etheridge sings two songs in an elimination episode which we hope sends homes the annoying "Bachelor" Jake.

NOVA: Mind Over Money (8pm, UNC-TV) - If you've got your mind on your money and your money on your mind, Nova can tell you why. It seems the brain actually misfires and makes us irrational when money is involved. A fascinating look at behavioral economics.

Glee (9pm, Fox) - Kristin Chenoweth returns as April Rhodes, to help Will save the glee club, while Sue Sylvester (Jane Lynch) puts her Cheerios (mostly Mercedes) on  a diet. Also, Kurt fixes his dad up on a date, hoping for a more normal family life.

Frontline: The Vaccine Wars (9pm, UNC-TV) -  A look at the controversy surrounding the vaccine regimen children face, including alleged links between vaccines and ADHD and Autism. A second episode of Frontline airs at 10pm ("The Dancing Boys of Afghanistan") looking at the practice of using adolescent boys for entertainment and sex by former warlords and businessmen.

The Good Wife (CBS, 10pm) - Alicia goes up against her former boss Jonas Stern, and considers using her knowledge of his dementia against him. Peter finds religion because, you know, it'll help with his appeal.

Sanford and Son (5:30pm, TV Land) - A "Sanford and Son" mini-marathon starts at 5:30, but the Aunt Esther episodes commence at 8:00. In the first one, Grady (Whitman Mayo, my favorite S&S character) accidentally causes trouble between Aunt Esther (LaWanda Page) and Uncle Woodrow. Next, Fred (Redd Foxx) helps Esther prepare to compete in a beauty contest. That's not a misprint.

The Incredibles (8:30pm, NBC) - The animated action classic featuring the voices of Craig T. Nelson and Samuel L. Jackson.

12 Men of Christmas (9pm, Lifetime) - It's going to be impossible to beat Kristin Chenoweth in this holiday-themed Lifetime movie. Check out Adrienne's review.

Saturday Night Live (11:30pm, NBC) - Blake Lively is the guest host and Rihanna performs.

Whenever I see Kristin Chenoweth on TV, I get excited.

She's so darn cute, this naughty mix of retro and modern.

She can do that rat-a-tat banter like in a Kate Hepburn movie, but she's far more girly.

She's what makes "12 Men of Christmas" (Lifetime, 9 tonight) worth watching.

Hank (8pm, ABC) - A new pilot starring Kelsey Grammer as a CEO who loses his job and has to face downsizing with his wife and kids. This hasn't gotten very good reviews, but maybe ole "Frazier" deserves the benefit of the doubt. I'm in for one show.

The Middle (8:30pm, ABC) - Patricia Heaton, Grammer's former partner from the Fox sitcom "Back to You," plays a middle-aged Indiana mom with a blue-collar husband (Neil Flynn from "Scrubs") and three kids.

Modern Family (9pm, ABC) - The premiere of this sitcom last week was laugh out loud funny. Tonight, Mitchell and Cameron sign Lily up for a Mommy & Me class.

Glee (9pm, Fox) - Our favorite songstress on our favorite show! Kristin Chenoweth stars as Will's former classmate, called in to help spice up the glee club.
