• How I Met Your Mother (CBS, 8pm):  “Marshall finds a letter he wrote when he was young, and it has a dramatic effect on him.” Up until then, he had completely forgotten all about Sarah Marshall.
• Cake Boss (TLC, 9pm):  “The crew makes a holiday-themed cake for a drag queen.” The holiday? Cher’s birthday.
• Diners, Drive-Ins and Dives (Food, 10pm):  “Guy Fieri visits North Pole, Alaska, for a taste of local Christmas favorites, including holiday ham with wild Alaskan cranberries; Reindeer hoagies; and “Santa” burgers.” For this trip, Fieri will be joined by a special guest: The Grinch.

• Charlie Brown Christmas (ABC, 8pm):  “In this Yuletide special (which first aired in 1965), the gang looks forward to presents, while Charlie Brown is upset by the holiday’s commercialism.” His hatred for ABC’s holiday repeats comes a close second.
• Disney Prep & Landing (ABC, 8:30pm):  “A veteran elf (voice of Dave Foley) is passed over for a promotion and instead gets paired with an eager rookie.” Not even Disney characters are safe from cheaper replacements.
• Outer Space Astronauts (Syfy, 9:30pm):  Series premiere. “Capt. Ripley invites aliens over to the U.S.S. Oklahoma for a pizza dinner, but the aliens want the ship, too.” Aliens want their pizzas to come with the works.

• Mythbusters (Discovery, 9pm):  “A gunslinging myth is put to the test, along with a notion spawned from the movie Speed.” The slower a vehicle gets, the more wooden Keanu’s acting becomes.
• Glee (FOX, 9pm):  “Will ponders an important decision as Emma and Ken’s wedding nears.” Should he get something off the registry or just buy them a gift card?
• Barbara Walters Special: The 10 Most Fascinating People of 2009 (ABC, 10pm):  “Walters 17th annual special includes Adam Lambert and Sarah Palin.” One waged a public war against a Johnston, the other got in trouble with ABC because of his Johnson.

• Bones (FOX, 8pm):  “Brennan’s father tries to persuade her to spend the holidays with him and a distant relative (Zooey Deschanel) rather than return to Central America.” After all, she is almost famous.
• Community (NBC, 8pm):  “A bully (Anthony Michael Hall) challenges Jeff, who’s also worried about failing Spanish.” The bully thought Jeff’s study group was demented and sad, despite being slightly social.
• 30 Rock (NBC, 9:30pm):  “Jack chances upon a former school flame (Julianne Moore) via a new social-networking site.” The site - MatchIMDB.com - could only be accessed by those with a SAG card.

• Supernanny (ABC, 8pm):  “A dad who works full time and a mom who works part time and is a full-time student need help with their three boys (ages 3, 5 and 9), the youngest of whom was kicked out of preschool and utters a profanity at Jo.” I sure hope that kid didn’t get on Jo’s frost-y side.
• Yes, Virginia (CBS, 8pm):  “An 8-year-old girl in 1897 New York tries to discover if Santa Claus actually exists and writes a letter to a newspaper editor as a last resort to find the answer.” Unfortunately due to industry budget cuts, the inquiry was answered by an intern.
• Sanctuary (Syfy, 10pm):  “Katie proves her worth by taking a gunshot wound for her team.” I remember when building a fire was enough to prove your value to the tribe.

• The Simpsons (FOX, 8pm):  “Bart decides he wants a brother after observing Lisa and Maggie’s bond when the power goes out during a blizzard.” Nothing cures outage boredom like a good brotherly beatdown.
• Dexter (Showtime, 9pm):  “Debra becomes privy to something she’s not sure she wanted to know.” Her brother is the man she’s going to one day marry?
• Christmas at the White House: An Oprah Primetime Special (ABC, 10pm): “Oprah Winfrey interviews President Barack Obama and First Lady Michelle Obama during an hour that also follows holiday preparations at the White House.” The lovefest will include a poem reading from Maya Angelou and cocktails served by Gayle King.
