DJ Swamp did a turntablist set at a DMC competition and at the end he poured lighter fluid all over the still playing records and set them on fire. That was kinda cool, but it only destroyed the records, not the turntables.
Other than that, I've gotta go with no, because that's a serious waste. I'd let 65daysofstatic do it, but that's about it. Actually, the first time I saw them they finished the show with Paul falling off the stage while playing the end of the song, and the drummer threw his whole drumkit at him, and then the mic stand. Nothing was broken, but it was pretty funny. So maybe that counts.
