Warner took Harris out onto the studio lot, and showed him the famous water tower with the Warner Brothers logo on it. "What does that tower say, Richard?" asked Warner. Harris replied "It says 'Warner Brothers." "Right," said Warner. "Now when it says 'Harris Brothers', *then* we'll do it *your* way."
