I don't know where Blake came up with this Knock Knock Jokes it started out with "a banana on your door and and it's sticky" and it evolved into every joke being something on your door and it's sticky. Wesley has started telling them too, but he leaves most of it out and just says any random item is sticky. The best is when everyone ignores Wes and he starts telling them to himself, maybe I can get that on video soon. Enjoy Jokes For Children
