Yeah. The grimace shake is fine, it's just a popular meme. And I pray for any child who believes it. Im also surprised that McDonald's is still going on with grimaces birthday. Here's how I heard about it: a imgflip post about mdonalds' grimace birthday game boy game, later the meme on YouTube, recently hearing that McDonald's official playlist has the somg undertale (oo I'm an undertale fan so this intrigues me). Oh crap this is a long comment, good luck
