That guy is wearing a helmet, but it doesn’t protect him from the dangers of mustard. Probably because mustard is something you eat. I’ve once received a drop of mustard on my head and I don’t think I’ve suffered a lot of brain damage although, I mean, I could be wrong. I’ve been wrong about a lot of things in the past such as: Yogurt is not a cat, I had to learn that the hard way, and you can not play the piano if your piano is resting precariously on top of the CN Tower.
And this here is a clear illustration of what mustard can do to your brain kids, so don’t do mustards or you’ll think cats are yogurt.
