One of the biggest muscles in the body is the brain. This is the game that flexes that muscle. Sees just how strong it really is. Though it isn't as strong as the tongue. That thing is god damn strong. It's like an elephant trunk, you know? Just all muscle! Also the brain is big... but the biggest muscle in the body is the gluteus maximus. That's right, you're ass is the biggest muscle in your body. How ashamed are you right now? For heaven's sake, shrink that fat ass and work out your brain. Be the exception! You're brain will be bigger than your ass! Be the first!
