The original title of this episode was "Bjorn to Be Wild." This is because it called for Albert Brooks to voice Bjorn, a Swedish tennis instructor, but Matt Groening thought it would be better to make Brooks' character French. This then led to them nearly calling the episode "Jacques to Be Wild". Interestingly, and nineteen seasons later, in "Coming to Homerica," the name was recycled to name a bunky, athletic-alike Ogdenviliian man of Norwegian heritage (another Scandinavian country), who seems to fall in love not with Marge, but with Selma instead.
The moon is seen to have three craters on it, much like a bowling ball when Jacques is dropping Marge off.
