It's becoming increasingly difficult for those Glee fans who already feel guilty enjoying the performances of New Directions' rival groups to root for McKinley when the show continues to gift us with really stellar performances from their competition. (We know we're supposed to want New Directions to leave New York victorious, but it would be so much easier if the other groups were all like The Hipsters.) With the stage set for Nationals, MTV has a look at those trying to defeat McKinley's own. First up: an all-female group performing the 2004 Usher, Lil Jon and Ludacris hit "Yeah," a cappella. The girls put a feminine spin on the party favorite by managing to mix in Lil Jon's "Get Low," 2pac and Dr. Dre's "California Love" and Mystikal's "Shake Ya Ass" into one high energy track. (Leave the staging and choreography to your imagination for now.) But since this a family show (we think?), Luda's astute cultural observation about needing a "lady in the streets but a freak in the bed" has been swapped for "you know you want a kiss on the lips though red." (Huh? Awkward, yet more appropriate, we suppose.) What?! O.K.!

It's obvious that young Artie will be fuming over not getting the chance to tackle this number first. Despite the disdain some have for Glee stars rapping (unfortunately he and Mr. Schuester usually get the brunt of it), there have actually been a few moments where these Lima losers manage to pull hip-hop and R&B off ("Bust Your Windows," "Blame It" and "I Wanna Sex You Up") but of course, also some very bad ones ("Thong Song," anyone?). So just to be safe, don't get any ideas about busting out Odd Future at Nationals, Schue.
