Watch the short documentary The Acrobatic Fly, filmed 1910.
Propped upon the tail-end of a match, a housefly performs astonishing feats, alternately juggling a series of objects - a blade of grass, a cork, a miniature dumbbell... Most extraordinary of all is the sequence in which the fly spins a ball twice its own size, while a second fly perches on top. In the final sequence, the fly repeats some of its earlier tricks while apparently seated on a tiny chair.
