So we had a bit of white board material, which we decided to use on the robot. From there, it came naturally to put some things on the board. (We’re thinking of putting witty phrases on the robot each match in the place of the “YOUR AD HERE” part.)
Just out of curiosity, is that a working phone number? If so, how many prank call have you guys gotten off of it by now? 
Very clever idea though, I suppose if you have the space you might as well sell it off to someone!
Yes, that is a valid number (at least in the 803 area code). It’s the main number to Columbia High School.
