My senior year in high school, my parents took my girlfriend and me on a vacation with them to Colorado. In order to maintain decorum, we got two hotel rooms - my girlfriend and stepmother in one, and my dad and I in the other. This was one of those hotel rooms where the air conditioner was a unit at one end of the room, blowing air at high velocity back toward the other side. My dad and I both have sinus issues, and we sleep with a fan blowing on our faces all year long. So, we each set up a fan on the night stands by our beds in such a way that my fan blew back toward the air conditioner, and my dad's fan was between my fan and the air conditioner, also blowing back toward the air conditioner. Picture a sort of wind tunnel created by this setup. The air conditioner blew air from one end of the room to the other near the ceiling. The air bounced off the wall, got blown back across the room by my fan, got sucked up by my dad's fan, and then blown into the flow of the air conditioner, where it started the cycle all over again.
And that's when it happened. My dad...how shall we say it...let one rip into the breeze of his fan. Where it quickly got caught in the wind-tunnel current and distributed throughout the room. The bad part was that because of the nature of the current, it kept getting circulated around and around, so that every few seconds you received a new full-body waft. I nearly died before I could crawl to the fans and turn them both off until the smell had dissipated.
