“Greatest Holiday Moments: TV & Film Countdown” (8 p.m., NBC): “Greatest Holiday Moments” is a special that lives up to its title with memorable clips from classics such as “It’s a Wonderful Life,” “A Christmas Story” and others.

“Merry Christmas, Drake & Josh” (8 p.m., Nickelodeon): During their four decades as a comedy duo (actually, it was more like four seasons playing teen stepbrothers on Nickelodeon’s “Drake & Josh”), Drake Bell and Josh Peck started out as cute, goofy kids. But by the series’ end in 2007, they were exhibiting the overage, desperately overplaying style of a pair of over-the-hill vaudevillians.

Never mind. They’re back, along with the rest of the “D&J” troupe including “baby sister” Miranda Cosgrove (now sort of a fox as the star of Nick’s “iCarly”). This uncalled-for reunion results in a special Nick movie, “Merry Christmas, Drake & Josh.”

Unlike the series in its prime, this film has minimal wit, maximum shtick and an unexpected mean streak. Peck, whose designated function was always to play Jerry Lewis to Bell’s Dean Martin, is so wound up in this movie he makes a showoff like Lewis seem like an introvert.

Bottom line: Kids will probably like the film. But adults who might not mind being in the same room with an episode of “Drake & Josh” will flee when this movie gets rolling.
