Like others have said the WWE does this with everything. They posts those little fact things after commercials and have shown stuff comparing them to every major sport and non sports shows like The Simpsons, Gun Smoke, Lassie, entire networks (including the ones their on), websites, social media stuff, charity contributions, basically anything. I wouldn't even call this a jab at the UFC.
