One man truly can make a difference.

Nobody is sure what 21-year-old Garrett Smith was on when he stripped naked and charged headfirst into a parked car on Tuesday night, but let's hope it was something. The alternative is even scarier.

Anaheim waitress Clarisa Vidrio, who was in the next car, believes he was after her. She certainly did at the time, and got so scared that she backed into her neighbor's fence. Then, Smith jumped on to the roof of her car as she tried to drive away (which certainly supports her position), and shattered her windshield. She drove into a wall to dislodge him, sending him flying across the parking lot. He got up and sprinted off, but was picked up by police down the block.
