So I'm watching the Train Wreck de France, and one of their recurring commercials is for Bridgestone Tires' new 'run-flat' thingamajig. It shows some guy in a nice BMW screaming down the autobahn when he runs over a board with a four-inch nail in it. Blah blah blah, yada yada yada, and the guy's glad he's got new Bridgestone run-flats which allow him to (per the small print) "drive at 50mph or less for 50 miles or less."
How the commercial ended: The guy continues screaming down the autobahn. Cue the world's worst commercial music (think the Mormon Tabernacle Choir on LSD trying to sing, oh, I don't know, some really teeth-grating aria).
How the commercial should have ended: The guy continues screaming down the autobahn... until his overstressed run-flat tire fails spectacularly, sending him into a bridge abutment at 200kph.
