12. Teach Me How To Understand Christmas
The Season 3 Christmas special/Glee parody has so many hilarious songs, including Troy and Abed's "Baby Boomer Santa," Britta's "Me So Christmas," and The Dean, Chang, Magnitude, Starburns, and Leonard singing their names/catchphrases as Christmas Tree Ornaments, but Annie's "Teach Me How To Understand Christmas" takes the milk and cookies.
In an attempt to bring Jeff into Glee club, the usually intelligent Annie performs this half song/half seduction where she acts painfully stupid. As the show goes on, she acts both dumber and sexier, ending with the hilarious line, "Boo Bee Doo Bee Doop Boop Sex!"
After her song, Jeff tells Annie she eventually hit a point of diminishing returns with the sexiness. Annie, still in character, replies, "What's a dimininininiwha." Alison Brie, who usually brings a great sense of competence to Annie, nails this hilarious, out of character scene.
Annie's plan works, and Jeff joins Glee Club. Had they performed this song, they might have made Regionals.
