Gene Belcher is known as a jokester, but he may not actually be joking when he refers to himself as a woman. One fan theory suggests Gene is actually transgender, or gender fluid. Here's the evidence: in one episode, Linda asks Bob if his penis is okay. Gene interjects "Mine's a nightmare, if anyone's wondering." He also has said things like "We're working girls now," and "I was born to be a mother."
In one episode, Louise even refers to Gene as the "good daughter." Others argue that Gene does project distinctly male behavior, so it is possible he's actually gender fluid rather than transgender.
One fan theory by Redditor Fatdude6 suggests Louise's bunny ears were written into the show as a nod to Marge Simpson. Originally, The Simpsons planned to air an episode where it was revealed Marge was hiding mutant rabbit ears under her hair. While the episode was scrapped, it was referenced in the arcade game. You can pretty clearly see bunny ears when Marge gets electrocuted.
I didn't realize a new season had came out, this show is one of my favorite animated shows and has been very consistent over 15 seasons. Been binging the season and it's nice for background noise also.
