Episode I most disagree with:

Was the one where Arnold's friend was called a nerd in the school paper and Arnold brought charges of slander against the paper for calling his friend a nerd and he had to prove his friend was NOT a nerd since slander is only illegal if its untrue and the way he did it was pointing out that people liked him and he said and I quote NOBODY LIKES A NERD.

That is BULL$HIT. NOBODY liking you is NOT part of the definition of being a nerd. For starters other nerds could like a nerd and it is still possible for a nerdy person to have friends and be liked.
