When in doubt, 'Blame It On the Alcohol' -- at least, that was the lesson in tonight's episode of 'Glee' -- and PopCrush has your recap.

Principal Figgins wants to warn the students of McKinley High about an 'epidemic' -- the dangers of underage drinking -- because of news of alcoholic beverages being targeted to kids through music. A shoutout to Four Loko, perhaps? Sue is now in charge of the glee club's Regionals rival, Oral Intensity, after shoving their previous coach down the stairs in a hilarious scene. Oops! Meanwhile, Will and Emma are seen flirting in the teacher's lounge, and Sue suggests that the glee club coach check himself into AA.

Puck urges Rachel to throw a party while her dads are out of town, and she's hesitant until she performs a snippet of an original, unemotional song about her headband for Finn, and he unintentionally pushes her to throw the bash -- despite Alcohol Awareness Week. The news spreads fast, and “The Rachel Berry House Party Train Wreck Extravaganza" is officially a go.

Unsurprisingly, Rachel's idea of a party is unlike anything anyone else had in mind -- what with the two drink limit and all. So Puck pushes her to crack into the liquor cabinet, and the Warblers and New Directions join sides for one crazy night of hitting the sauce and high school drunkenness. Finn labels the ladies with their drunk types -- Santana, the "weepy, hysterical" drunk, Lauren Zizes and Quinn, the "angry girl" drunks, Brittany, the girl "who turns into a stripper" drunk, Mercedes and Tina, the "happy girl" drunks, and Rachel, the "needy girl" drunk -- which offends Rachel and puts her in the mood to play spin the bottle.

Suddenly, all of the glee club kids are making out, but when it's Rachel's turn and the bottle spins to 'Blaine Warbler,' Finn regrets ever opening his mouth. Rachel and Blaine lay down a charged duet of ‘Don’t You Want Me’ (Human League), but in the end, it's confirmed that the 'Glee' newcomer is gay when he wakes up hungover in Kurt's bed -- or is he?

The next day at school, Artie provides the glee club with bloody marys -- "the hair of the dog that bit you" -- and he and Mercedes perform a club-worthy version of Jamie Foxx feat. T-Pain's ‘Blame It (On the Alcohol).’ Will thinks the song glorifies drinking and wants to nix the performance for the school assembly, and Coach Beiste takes him to a honky tonk bar so he can let loose and relieve some stress. Beiste makes her 'Glee' singing debut while Will makes his bar singing debut in a duet performance of ‘One Bourbon, One Scotch, One Beer’ (Amos Milburn). Back in teen-land, Blaine struggles to re-discover himself after kissing Rachel, and agrees to go on a date with her -- much to Kurt's dismay.

At the alcohol awareness assembly, Brittany shines as Kesha in a New Directions ensemble performance of ‘Tik Tok’ -- while the whole glee club is under the influence of Rachel's homemade concoction. The kids learn their lesson when the purple stuff backfires and sends them all into a vomiting frenzy in the school gym, and Brittany ends her song with a message to the students, "Everybody drink responsibly!"

Sue says the glee club is spiraling out of control and blames it all on Will, whom she received a drunk-dial from (intended for Emma) a few nights before, and the glee club coach vows to cut out drinking. In addition, he has the kids sign a pledge to do the same, and urges them to call him if they ever have a slip-up.

Season 2, Episode 14 was one wild party! Head back to PopCrush next week -- and beyond -- for a play-by-play of each 'Glee' episode.
