'The Rocky Horror Picture Show' Cheat Sheet: Here's What You Need To Know Before Tonight's 'Glee'!

If you're a fan of the cult classic "The Rocky Horror Picture Show" there's no doubt that tonight's new episode of "Glee" has you shaking with antici...(say it!)...pation! But for all you Crushers who aren't familiar with the 1975 movie musical adaptation that spawned countless theatrical productions around the world and midnight screenings that thrive on crowd participation, we'll catch you up to speed.

The film, which is a campy blend of music and science fiction, tells the story (through a criminologist narrator) of recently engaged teenagers Brad and Janet (played by Barry Bostwick and Susan Sarandon) whose car breaks down in the rain one night and they soon find themselves at the creepy castle of one "sweet transvestite from Transylvania" named Dr. Frank-N-Furter (the incomparable Tim Curry).

It turns out, they've stumbled upon the Annual Transylvanian Convention and soon meet Dr. Frank-N-Furter's band of bizarre cohorts (cue the showstopper "Time Warp"!). Among the bunch, there's his servant, Riff Raff, Riff Raff's sister Magenta and a groupie named Columbia. They've all come together to see the unveiling of Frank's creation, a hunky Frankenstein named...Rocky Horror!

The whole strange evening gets even stranger as it turns into a night of murder (including the poor ex-delivery boy named Eddie [played by none other than Meat Loaf!]), seduction (Frank seduces Brad and Janet, while Janet turns her affections towards Rocky, and, well, let's just say everyone in the castle seems to enjoy the company of one another), aliens (we learn that Frank and friends are actually from the planet of Transsexual in the galaxy of Transylvania), and of course, some unforgettable musical numbers.

Sound crazy? It is, but it's a totally weird and wonderful movie-going experience! Here's to hoping the cast of "Glee" can pay homage to one of the most beloved B-movie musicals of all-time!
