Knock knock.
Who's there?
Control freak.
Con...
Ok, now you say, "Control freak who?"
Listen up, smarty pants, Explain bear is here. This is a knock-knock joke, see? The dude sets you up to say "Control freak who?" because it sounds like "Control freak, who?" which is what a control freak would actually say. It's all about playin' with words, which is hard for dum-dums like you, who probably still think the Earth is flat. Also, you probably watch the news for fun because you are so boring.
