The kinky best-seller Fifty Shades of Grey has titillated millions of readers and moviegoers -- and is officially a pop culture phenomenon. The next logical step is, of course, a musical parody. 50 Shades! The Parody is a hilariously naughty sendup of the book, featuring a trio of girlfriends reading the novel for their book club. As they devour the steamy scenes, the characters' affair comes to life before their eyes in a very ... stimulating way. A hit in theaters all over the nation, 50 Shades! is a gleefully bawdy roller-coaster ride through the book, featuring original songs like "They Get Nasty" and "There's a Hole Inside of Me." You won't want to miss this laugh-out-loud night of music, comedy and sexual shenanigans when it comes to the perfect place for such a show: Las Vegas and Bally's Window's Showroom.
