I work in an office and have a window on which I have several Spider-man figures. Once a month for the past three months these figures have been knocked off the windowsill. In December I just brushed it off as an accident. In January I knew it was no accident. In February I put a post-it note on the windowstill that said, "I will clean the windowsil myself. Thank you!" I thought that would solve the problem as it's obviously the cleaner doing this. Today again my spideys were knocked off the sill. I have a sneaking suspicion that it's a feminazi who is triggered either by spider-man or by the various civil war books around my office (I write books about the civil war.) Any ideas on how to deal with this? I'm not getting rid of the spideys, my son plays with them when he comes to my office. I've documented every instance this has happened but feel it's weird going to my boss about something so petty.

Edit: Thanks for all the advice. Based on everyone's advice, here's what Im going to do. I'm going to increase the Spidey population on the windowsill by 600% and install a motion detected nanny cam in my office to catch her reaction. Then right before she does her regularly scheduled Spidey smash I'm going to put a special case there so she can't touch them and my son and I can still enjoy their presence.
