People love dramatic readings; there's something about a vocal-fried puree of Antonio Banderas and your local Shakespearean trouper, applied to colloquial or poppy texts, that deepens voices the comedy world over. And enough people presumably like LMFAO's "Sexy and I Know It" to get it to No. 1 on the charts.
Those charts take radio airplay into account, so it's natural that top 40 stations would want to josh about the thing they've had to play hour after hour, right? There are so many ways to pronounce "look at that body"! And if your geographic location means you can get Evan Rachel Wood's father, veteran Raleigh theater director Ira David Wood, to perform the reading instead of one of the DJs, so's the better. This is probably the best thing that'll be associated with the North Carolinian drive-time dudes on Bob and the Showgram this year*.
