Caveman Speak

''Me Ookuu. Me caveman. Me not intelligent enough to speak fluent English. ME WANT TO BE YOUR FRIEND.''

This is how cavemen and other low-intelligence characters speak. In Real Life, cavemen only used grunts and other simple noises to communicate with each other, not meaningful language. Caveman Speak, as to be expected, is a lot simpler than proper English for reasons obvious.
