I have six locks on my door all in a row. When I go out, I lock every other one. I figure no matter how long somebody stands there picking the locks, they are always locking three.

Boosler’s joke riffs on the anxiety of personal security and the sometimes-irrational rituals people adopt to feel safe. The logic is deliberately flawed—locking “every other” lock doesn’t create a self-locking door—but it mimics the way worry can produce elaborate systems that sound clever in the moment. The humor comes from treating a home-security measure like a mathematical proof, then revealing the absurdity: the imagined burglar is trapped in an endless loop of progress that never reduces the number of locked locks. As with much stand-up, the line also satirizes consumer culture’s promise that more gadgets and precautions equal control over uncertainty.
