Zakk Wylde, Lars Ulrich and Skid Row Walk Into A Bar...

It led to a celebrated story in which Lars Ulrich wound up handing cups of Wylde's urine to fans, thinking it was beer. But the guitarist is more surprised the event took place at all.

He recounts the memory in his new book Bringing Metal to the Children, and tells Guitar International: "It doesn't make any sense. I didn't want to lose my spot in line for drinks. I was putting them on the bar and I was going to throw them out when I was finished pissing � there was a garbage can a few feet away.
