Malone's Law

This is a corollary of Godwin's Law which states that if an online discussion about rock music goes on long enough, sooner or later someone will compare some band or performer or a situation to Roger Waters, Peter Gilmoure and Nick Mason and the acrimonious breakup of Pink Floyd, the point at which effectively the discussion or thread often ends.

Ian "Panic! at the Disco are now just Brendon Urie's solo project."
Shane "Just like Pink Floyd after Roger Waters left, it was nothing but David Gilmour's ego trip."
Ian "Malone's Law! this conversation is OVER!"
