I've heard of people putting a blow-up doll in their passenger seat so they can drive in the carpool lane, but this is ridiculous:
Woman Drove Around With Corpse For Nearly a Year
Police say the woman used baking soda in an attempt to dissipate the odor.
Authorities say a woman drove around with a mummified corpse for about ten months before the body was discovered by police.
Police say the woman tried to cover the remains with pieces of clothing.
