The second time this episode aired changed the last caption to: "Now stay tuned for three Seth MacFarlane cartoons" (referring to Family Guy, The Cleveland Show, and American Dad!) and the syndicated version changed it to: "Think of all the things you could be doing instead of wasting your time with this show."
