What's with the gold turd storyline in American Dad?
I realize that they've just been showing reruns lately, but I recently saw one of the "golden turd" detours in an American Dad episode. This plot line began when Roger (my favorite character on the show) shat a jewel encrusted golden turd. Everyone who discovers it gets really greedy and violent, often killing their friends or loved ones.
Is this a reference to anything? The characters involved in this subplot aren't even remotely related to the regular show, and this storyline doesn't even try and be funny. It takes the form of a serious, sinister drama.
Any ideas on why it's there? Any ideas on how, or if, it will come to a resolution? Every time I see it, I just scratch my head in confusion.
