So the new So You Think You Can Dance audition rounds kicked off last night, and among the fancy-footed hopefuls were a few familiar faces (and feet).

Like rubber-limbed B-boy Twitch, who narrowly missed making the finals last season (Hok snagged his spot). Or triple-jointed Phillip Chbeeb, who didn't make the cut last year despite his astounding arsenal of dislocated-dancing tricks, but after a year of training returned for a stupendous and successful second tryout last night. Or jumpdancing masked-marauder The Gold Inferno who--despite Nigel Lythgoe's (presumably joking) protest, didn't even make it to the choreography round this year.

But most importantly, for season 4, SYTYCD brought Sex(y) back.

Yes, the self-stagenamed "Sex" (aka David Soller, the "21+" amateur hoofer who looks like the lankhaired lovechild of hippie Neil from The Young Ones and a less brawny/more scrawny Andrew WK) returned for this third--SURPRISE!--failed audition last night.

But who cares if he didn't make it? A SYTYCD season without Sex would be like a season without Mary Murphy's hot-tamale scream. Without genius judge/choreographer Mia Michaels' magically tear-inducing, Emmy-winning dance routines. Without some eightpack-abbed ballroom-dancing himbo ripping off his breakaway shirt at climactic moments in order to attract the cougar vote. Without a token Schwimmer spawn in the competition. Et cetera. Because a key part of all the SYTYCD audition-round fun is some Sex appeal.

If you're unfamiliar with the joy of Sex, here are a couple clips of him getting his groove on in SYTYCD seasons 2 and 3:

And Mia Michaels must have had Sex on the brain this season, because she Freudian-slipped his memorable moniker before he even sashayed into the audition room last night:

Mia, you're blushing!

Anyway, when everyone's favorite delusional dancer returned to Sex up Mia et al with the smooth moves he's learned during his "many, many years" of "extensive formal training" with "many master choreographers and teachers in the country," Mia even claimed that he had potential for growth. (She admitted such a kind critique might have been the result of several glasses of wine, though.)

Wow, this is proof that with practice and perseverance, and probably a whole lot of wine, Sex can improve! A lesson for us all.

See ya in season 5, you Sex-y beast!
