Who said it?: Columbus
The story behind the quote: Zombieland is a 2009 film about, well, zombies. However, unlike previous films of the genre, it is not a horror movie. It’s more of an action-comedy movie about a group of people trying to survive after the zombie apocalypse. Another thing that makes it different from other zombie films out there is that the survivors are actually pretty good at going about living in the world. One of the reasons why they are so successful is because of the rules Columbus (played by Jesse Eisenberg) created. He created a whole list of them and they all proved pretty effective in ensuring that he lives.
The quote comes from the 4th rule, which is “Double Tap.” In most zombie movies, the survivors shoot at zombies and, when it falls down, they do the stupid action of getting close to check on the supposedly dead body. Columbus suggests that people shouldn’t be stingy with their bullets at a time when survival is the main goal. Shooting the zombie once more make sure that they’re downed.
Geek wisdom: Like in real life, people should always make sure about stuff. There’s no harm in checking and re-checking if what you did is correct. For students, it could be the answers for a test. For people at their jobs, it could be the work you’re gonna submit to your boss.
“Double tapping” just takes a few minutes of your time and it’ll give you peace of mind that you did your job right.
