Calcium carbide in her potted plants (if she has any in her office), dead fish behind her hubcaps, dead fish in her cabin air filters...if you know anyone in the vetranary/dog grooming business that can get you some dog anal gland juice (or if you have a dog with overactive glands and don't mind gloving up and fingering its ass) that stuff is horrid. Or you could go the nerdy route and terrorize her through the computer.
