Fortunately, I have proof. Look no further than the current controversy on home mail delivery. Perhaps that explains why letters take a week to arrive from Gilroy. You give chain-smoking, galactic conspirators postal access to your home, and anything can happen. This should come as no surprise.
Many extraterrestrials hold part-time jobs as chimney sweeps, or live next door.
It makes things all so convenient. Combine that with postal worker home mail delivery, and there will be no stopping them. They ll pump that immobilizing vapor down your flue in a heartbeat, melding with your DNA and transforming you into a fellow conspirator-zombie. It's kind of a cold fusion thing. It's important to be sharp-eyed.
