a funny one that come to mind was sometime back in 2000-2001... a doozie of a show @ the Colorado Brewing Co.... there were a few non-regulars there before they started playing, but shortly afterwards, they all got up & left.....
"Buquebus, Buquebus, Buqeeeebus" turned into "we\'llcleartheplace, we\'llcleartheplace, we\'llcleeeartheplace"
