I loved the Facebones/Scientists explanation of Moshing on the bonus DVD with Dethalbum II.
"Someone who drinks urine."
"Not my own but your mother's..."
*lots of interrupting and gibberish*
"Menstrual flow."
And the bathroom short.
"I can't believe you've never used the bathroom on stage before, its like the oldest trick in the book."
"Zeppelins did it!"
"Yeah, Steely Dan, Rush..."
"Olivia Untons-John and Hans Travoltas dids it too!"
