On last night’s episode of “Community,” the gang of pop culture experts engaged in a vicious and very funny “Glee” parody.

Of course, this isn’t the first time the NBC comedy has mocked show choir absurdity. “Glee”-sentment has been expressed in the past on “Community,” including this moment from last season. But this week marked the first time that the study group committed to New Directions mockery in a yuletide context that featured a full slate of original Christmas music. At one point, Abed (Danny Pudi) even watched the horrible “Inspector Spacetime Holiday Special,” an obvious nod to the “Star Wars Holiday Special,” which will be sent up during next week’s episode of “Glee.” That’s a lot of meta right there.

Anyway, it only seems fair to share clips from some of the musical numbers from last night’s “Community,” since we do that here for “Glee” on a weekly basis.

First up: Troy and Abed’s “Christmas Infiltration” rap, the finest seasonal hip-hop song since Run-DMC’s “Christmas in Hollis.” Grade: A.

Next: “Baby Boomer Santa,” Troy and Abed’s appeal to Pierce (Chevy Chase) based on the fact that Baby Boomers believe they are responsible for creating everything that has ever existed in pop culture. “You’re welcome for the gift of the world,” croons Pierce at the end. I’m so glad somebody thanked the Boomers for doing something. They really don’t get enough credit or attention. Grade: A+.

Young children innocently croon “Happy Birthday, Jesus,” and Shirley (Yvette Nicole Brown) unleashes her inner Mercedes. Grade: B+, only because I wanted Shirley to sing more.

Annie (Alison Brie) manages to be sexy and also comment on gender yuletide issues with “Teach Me How to Understand Christmas,” a “Santa Baby”-style number that reduces her IQ so drastically that by the end, she can barely form a coherent sentence. Grade: A.

In “Planet Christmas,” Britta (Gillian Jacobs) destroys the Christmas pageant when she is intentionally upgraded from her role as mute tree to lead soloist in an effort to free the study group from its glee club commitments. Obviously, this ruins their chance at going to regionals. Whatever “regionals” are. Grade: D for skill, B+ for intentional comedy.

And lastly, in the episode’s stinger, a “Community” version of “Carol of the Bells.” I’ll never be able to listen to this song again with hearing Ken Jeong say “Chang,” repeatedly. Grade: B+.
