When I was a kid at school , just 5yo, I went to the local show, and their was a guy there doing a Flea Circus. He had them set up in a glass case, and I remember seeing a flea riding a small bike on a tightrope, also a dancing flea to music. Now I remember seeing it, but I also went to the next tent, and saw a womans head on a spider body, crawling around on a stage, at the end of the performance, the curtains closed for a minute, and they opened and the womans head was back on her body. It all amazed me, but I was five, so easily the wool was probably pulled over my head. But I can vividly still remember that flea on the tight rope.
