Hypo Luxa is the "producer" secret identity of Al Jourgensen of Ministry. In 1991 he was called in to do a re-mix of the Red Hot Chili pepper's "Give it away", the first single off Blood Sugar Sex Magik. It was not going well and depending on who you talk too, he brought a chicken into the studio to help make it right. There's a Cuban superstition where you kill a chicken and it absorbs all the bad spirits, but he kept this one very much alive and simply blew pot smoke in the chicken's face and set him down on the mixing board where it proceeded to crap all over the channels and everywhere it crapped they either erased that track, or emhasized it in the mix. Thus, it became known as the "chicken shit mix".
I love random acts of music production like that. Not only is it a great story, but I'm sure you get a 50% chance of improving the mix by taking it out of human hands in certain places.
"The chicken was put on a podium with a strobe light between two speakers, and it started going to the beat, that's when they knew the mix was done. (Al also claims to have driven motorcycles around in the studio)"
There's a small blurb about it here in a Ministry faq (search for "the chicken incident"), I first heard about it on Alan Cross's radio show.
