Trivia

 * It's heavily implied in this episode that Moe Syzlak is unable to vote due to being a registered sex offender.
 * This is notably one of the few episodes where Homer's perspective on a concept actually proves to be correct, as he imagines quite correctly what a Think Tank is when Lisa suggests it. This fact is even noted in the episode when, shortly after imagining it, sees his family staring at Homer as if completely shocked, and Homer says "What? Not allowed to get one right?"
