I find it interesting how Frink has no problem with “moron,” as far as I am aware, despite its original definition being “A person of borderline intelligence in the former classification of mental retardation, having an intelligence quotient of 50-69.”
Original definition means nothing. Times change. No one uses moron for anything but an insult anymore.
The same can be said of “retarded” in most places. “Mentally handicapped” and “special needs” are now the norm; at least in Canada.
