A little more than two years ago Sharknado first crept into our lives. Despite poor acting, abysmal writing, and dubious science, the Syfy flick became a surprise hit after trending on Twitter during its premiere. Each re-airing drew a larger audience than the last on its way to creating a juggernaut for the network, proving there's such a thing as "so bad it's good." Sharks and humans killed each other without hesitation or quality animation to boot, but we couldn't look away. And Syfy certainly couldn't resist a sequel and a threequel, given our embrace of the shit show. As we prepare for Sharknado 3 to drop tonight, we're taking a look at the Sharknado moments that captured our hearts and numbed our brains. Revisit the best killings in glorious GIF form.
