Based on the muppets, the professor CAN understand beaker. So I will proceed with the assumption that even though I speak like beaker, people CAN in fact understand me.

If my friends and I SPEAK like beaker does that mean we understand beaker?

If people can understand beaker then it its not really a big deal. If you personally speak like him, you'll sound silly, while if everyone does, it won't make a difference. In fact it would be good because everyone would speak the same language. However, if people can't understand it. The personal one would suck, but the global would lead to the total collapse of society.
