portrait arts

Does anyone have any theme ideas to use in a self-portrait drawing/photo? For my art class we have to come up with a theme and bring in props to be photographed with and then we have to use the photo to draw a self portrait. Does anyone have any creative themes or prop ideas? Some people are doing things like science related (with goggles, test tubes and equipment) superheros, alice in wonderland, and a light bulb thing (showing a bright idea). I need something unique and I can't think of anything that I like.
