Victor Salva's 2001 movie Jeepers Creepers may have taken its name from an old school pop standard, but it apparently didn't take any lessons in good decision-making.
Gina Philips and Justin Long star as brother-sister pair Trish and Darry Jenner, two college kids homeward bound for spring break. On their journey from long lectures to lazier days spent vegging out on their parents' couch, Trish and Darry encounter something pretty gnarly: an old man tossing what looks like dead bodies down a pipe in the ground near an abandoned church. Now, we don't know about how strong your sense of inquisition is, but we'd definitely ditch the scene and drive away, content with not ever discovering the stranger's grotesque activities.
Darry, on the other hand, simply can't help himself, and chooses to investigate the situation later on by climbing into the pipe to see where it funnels out. Down he slides (and lands at the bottom with a jarring thud), a choice that eventually leads to more horrifying findings and unleashes the titular Creeper, an ancient creature who pursues Trish and Darry and hack-slashes its way through their hometown.
What makes Darry's dumb choice even worse is that Trish straight-up calls him out on his stupidity before he commits to it, saying that shimmying into the dirty metal tube to find out if dead people lie below is the same kind of pea-brained decision characters in horror movies make. Clearly, we don't disagree.
