In the crowd of clones in Send in the Clones, Peter Griffin from "Family Guy", a Homer with glasses and a Homer drawn in the same design as he had appeared on "The Tracey Ullman Show" in 1987 appear alongside normal Homers. In regard to Peter Griffin's appearance, Skwigly says this is "a sly dig at the likeness of the two characters". "The Simpsons" staff noted that it was a joke at how "Family Guy" was a clone of their show. There was originally going to be a second joke involving "Family Guy", but as the show had recently been cancelled, the staff of "The Simpsons" didn't want to "kick 'em when they're down", so they cut it.
