The husband called the paramedics, who broke into the car because the doors were locked and Linda refused to remove her hands from her head. When they finally got in, they found that Linda had a wad of bread dough on the back of her head.
A Pillsbury biscuit canister had exploded from the heat, making a loud noise that sounded like a gunshot, and the wad of dough hit her in the back of her head. When she reached back to find out what it was, she felt the dough and thought it was her brains. She initially passed out, but quickly recovered.
Linda is a blonde, a Democrat, and an Obama supporter, but that could all be a coincidence.
The defective biscuit canister was analyzed and the expiration date was from 2008, so it was determined to be Bush's fault.
