Let's be frank: motor vehicle accidents aren't much fun for anyone. But when a 27-foot-long tube-steak spins out on a snow-covered highway, it's bound to generate some grins. That's what happened Sunday to an Oscar Mayer Wienermobile (at least it didn't roll over). The two 22-year-olds in the vehicle knew they were in hot water when they hit an icy patch, but they weren’t hotdogging. It was not an experience they would relish, but they are none the wurst for wear.
