Hey GB, I thought about that when I wrote it, but being it's from a movie that was made probably before I was born and it's a relatively commonly used phrase, and it's not an image, I figure it's probably safe from the watchful eyes of bored litigators.
It can be easily changed to something like "Clash of the Year" or anything else somebody more creative than me might think of, It was just the first thing that popped in my head. I also thought about, "Let's get ready to rumble" but those guys are very anal about their copyright so I decide against that one.
I'm open to any "Slogan" suggestions from anyone that might be more appropriate for the design, it's a very simple task to change it. I'll admit I didn't put a whole lot of time into this design. Thanks for looking out for us.
Bob
