Of course, the arguments on how to best worship started pretty early-Cain and Abel, I believe? Hopefully we won't resort to such drastic measures to settle our disagreements, though!
Except the argument was not about Abel thinking Cain's style was wrong and visa-versa, it was the "Worshiped" rejecting Cain's style.
They were both told to set up a line-array, with a 4 boxes per side, stereo configuration, and to be ready by 6pm. Abel did. Cain showed up at 6:30pm with a single Mackie on a stick. Then started screaming, "I need a 110 outlet! Get ready to be blown away!". Abel, "Did you not read the rider?" Cain, "I got your rider right here!"
