Edward Robinson Math

Listen up, buttercup. So, you take "Edward Robinson" and "Grant Wisler," right? Add 'em together and you kinda get "WHAT THE FU**?" It's like a word puzzle, but not a good one. You know, like when you try to do your taxes. And just like your taxes, this "joke" doesn't make a whole lotta sense. And people who don't understand it are probably smarter than the person who wrote it.
