When I was a kid, still in high school, I worked a milk run (delivering milk to houses. Does that job still exist?).
There were 2 of us delivering, and the driver. We rode on the back of the truck, loading the carry-crates while the driver took us from point to point.
One of the other guys who worked with us occasionally was a Greek dude (probably irrelevant, but hey), who loved licorice. Unfortunately when he farted, he could clear us off the back of the truck with the stink. Bear in mind that the truck was like a short wheelbase flatbed with a canopy. It was all open to atmosphere at the back, but this guy's farts were so foul that they defied the breeze and hung around like little stinky eddies between the milk crates.
Hey, I think I've told that story before...
