With respect to your deep-cut Boyz II Men playlist, we've found an even hotter cause of a two-hour traffic jam: 76,000lbs of beef ribs bursting into flames and filling the air with BBQ goodness.
It all happened over the weekend on a Southern California highway, when the back wheels of a semi's trailer started sparking, eventually setting the entire shipping container ablaze. That trailer just happened to contain 38 tons of ribs, so instead of getting blasted with a stinging, ashy smell of awfulness, the surrounding Ludlow area was greeted with a "wonderful BBQ beef rib odor", according to the official San Bernardino County Fire Dept report.
It took about two hours and 6,500gal of water to contain the fire, but no one was harmed... except maybe Louie Anderson, who had to wait for another shipment of beef. But on the plus side, California smog never smelled better.
