"An Obnoxious Retard"
I was watching Ebert and Roeper's review of Freddy Got Fingered and I was surprised to hear Roger Ebert refer to Freddy Got Fingered as being about "an obnoxious retard named Freddy." The contrast with what's acceptable to say nowadays, and that it came from Ebert who was typically stuffy and prudish, is almost as funny as hearing Freddy Got Fingered described in normal person terms by a movie critic like Ebert.
