Arnold Became Such a Jerk...
In the first few seasons Arnold was a friendly nice kid who was abit smarter than his age and for his own good at times but sometime around before Sam and Maggie came around and especially after, he became so jerky to everybody and altogether loathesome. Arnold was always rolling his eyes and folding his arms and seemed generally irritated by everybody in those last couple years. Thank goodness the show didnt last any longer than it did.
