"Is that fan flung fecal matter I see?"
LOL, reminds me of how we once put this in our HS "Underground" newspaper: When the excrement hits the air circulation device.
Me and the other "conservative" fought for that sentance, as opposed to the shorter one!
"Feces made contact with the ventilator."
O'course, that's back when our parents were working for NASA or Air Force and the kids picked up the lingo.
