The signs read 「偶然だぞ」 or gūzen da zo, which translates into It’s Accidental. Probably not the most appropriate sentiment when your favorite baseball player steals a home run.

So what caused this blunder? Online translators, of course. As illustrated below, when entered into Google tranlsate, the Cubs’ slogan becomes the inadvertantly commical phrase that ended up on the placards (much to the delight of the Japanese blogging community, I might add). Had the fans tried the more gramatically correct “It’s going to happen”, they would have gotten 「それが起こるだろう」, which would have been a vast improvement. Just some food for thought :D
