"In Poughkeepsie, NY at the final show of Strapping's tour with Meshuggah in the Spring of 2003, Devin walked on stage during Meshuggah's set with a bucket and a newspaper. He dropped his pants, sat on the bucket, and began reading the newspaper. As Meshuggah played on, Devin defecated in the bucket, then displayed the results to the crowd."

did this really happen or was someone just in a funny mood on wikipedia today?

Actually, it happened. You can see the pictures of it on the easter egg of the "For Those Aboot To Rock" DVD from Strapping. It's a little tricky finding the easter egg located in the extras section of the DVD on a home player console, but it's really simple if you play it on a PC because you can go right to the chapter (Windows Media Player recommended)
