Perhaps they'll invent one that will remove images from ones memory. I've a few of my Stupid Sister Viva that I'd pay to never see again.
It appears I’m enjoying a relaxing day at the salon, but actually darling I’m having the Retinal Scan Cam downloaded. It’s an extraordinary invention that plants a temporary “film” onto the eye’s retina so that all images I see for the next 12 hours will be downloaded onto a state-of-the-art imaging device. My eyes will essentially be cameras for the next 12 hours. Of course my location is top secret. For now… you’ll see for yourself soon enough!
