Weird! Real Life Flea Circus! (by britishpathe)
Real Life Flea Circus! Filmed in Paris in 1949, this genuine flea circus sees some very big fleas pulling various miniature vehicles across a table. They are harnessed by a thin wire. Rather disgusting! However, until about 1930, performing fleas were in fact a main carnival attraction.
