So on the January 24th, 2013 episode of Glee they decided it would be cool to steal Jonathan Coulton's arrangement of Baby Got Back, perform it on their show, and sell it next to his on iTunes without paying, notifying, or even crediting him. They certainly don't even try to hide where they got the idea for this cover from, as in the iTunes version they use Coulton's own lyrics at places rather than Mix-A-Lot's original words, such as the blatantly obvious self-referential "Jonny C's in trouble" line. https://soundcloud.com/alacrion/joco-v-glee What's worse is that there's some evidence that the Glee producers were too lazy to even rerecord their own tracks for the cover and they just overdubbed and remastered Coulton's karaoke version. If you listen to the tracks side-by-side this seems quite plausible, but the smoking gun (or smoking duck) in this case is that Coulton uses a loud duck quack sound effect in his recording to bleep an expletive, and this quack was part of the music mix and not in the vocal track. There's some evidence that some unusual EQ was used in the Glee version of the song at that "quack" spot - the sort you'd need if you wanted to isolate and remove a sound. http://geeklikemetoo.blogspot.com/2013/01/about-that-quack.html For anyone who doesn't know who Jonathan Coulton is, he's a former codemonkey turned geek rock star who writes clever and/or humorous songs pulling from a range of nerdy topics. And he's the guy who wrote Still Alive and Want You Gone for Portal and Portal 2. Fox's response so far has been that Jonathan should simply thank them for the exposure and drop it. It's a sticky situation in terms of copyright, because I have to assume Fox's lawyers feel covered on this, but regardless of the legal implications this is morally and ethically shitty thing for them to do. And that's what you missed! GLEE!
