Last night's (Feb. 22) episode of "Glee" was one big party, but was probably not suited to some of the show's younger Gleeks. When underage drinking becomes a problem at McKinley High, Principal Figgins declares "Alcohol Awareness Week" and commissions the New Directions to perform an anti-drinking number for the students.

Rachel, who is struggling to write original music for regionals, admits she has never had a drink. Believing she needs more life experience to write music, she lets Puck convince her to throw a party while her dads are away, (on the "Rosie O'Donnell Cruise"). We're not sure being drunk will help her write acceptable lyrics, but it can't possibly get any worse than her first effort, "My Headband."

The party turns into a wild night, and Rachel turns out to be a pretty cool host, despite wearing your grandmother's nightgown. The "Glee" kids play spin the bottle, and Rachel kisses the formerly definitely gay Blaine. The unlikely couple performs Human League's "Don't You Want Me." Blaine and Rachel are great together, but we're still Team Blurt (Blaine and Kurt) so we're furious.

The partygoers show up to school hungover, and they perform Jamie Foxx and T-Pain's "Blame It (On the Alcohol.)" We honestly think this version might be better than the original.

Mr. Schuester isn't sure he can lecture kids on the dangers of alcohol when he hasn't partied himself. Coach Beiste takes him to a honky-tonk bar and gets him sloshed, and he sings George Thorogood's "One Bourbon, One Scotch, One Beer." Will's version isn't bad, but we can't help but feel like you have to be kind of tough to do that song justice. Will Schuester? Not so tough.

Will tries to drunk-dial Emma, but ends up leaving a slurred message for Sue. Rachel, determined to prove to Kurt than she and Blaine have chemistry, kisses Blaine -- after which, he declares that he is "100% gay." The New Directions perform Ke$ha's "Tik Tok" at the assembly, but the performance ends in disaster in the form of projectile vomit.

The kids are spared suspension, but Will is embarrassed when Sue plays his drunken voicemail over the loudspeaker. Will asks the "Glee" kids to pledge that they will not drink until after nationals. Game on; cue that warm, fuzzy feeling.
