Israeli glamour model Orbit Fox posing with a snake.
The snake in question was unable to hold it's urge to nibble on Fox's assets.
When Fox was rushed to the hospital for a tetanus jab, everybody has became totally unaware that actually, the snake is the true victim here. The snake died shortly due to silicon poisoning that came from Fox's prized possessions.
