The best CBG line ever came when the nerds took over Springfield full of Utopian dreams (nice satire of the liberal mindset) and proclaimed that, in line with Vulcan ritual, sex would only be permitted once every seven years. "For some of you this will mean much less sex. For me, much, much more."
Another great line in that same episode--
Chief Wiggum: "Geez, how many gazebos do you she-males need?"
