I´d argue that The Fairly Oddparents used to be funny in it´s early Seasons. A good Example is the Episode where Norm and Crocker team up and because they are in the Desert you expect Crocker to run into the Wall, but instead he knocks on it and then gets squashed by a Rock. Of course, the Show always had Running Gags and "then the Opposite happends" Jokes, but those become more common after the Show started suffering from Seasonal Rot
