I have an inside joke with my cousins. They had never seen Gravity Falls, so whaen I told them about the show they started laughing. I asked them why, and they said gravity can't fall, according to the laws of physics. THen, every time I mentioned Gravity Falls they would say "HeeHee, Gravity Falls!"
