Exploding lavatory chain pull joke

This joke, from the first half of the 20th century, comes from the time when toilets were flushed by pulling a chain to release the water from an overhead cistern. When the unsuspecting person tugs on this pull, it comes right off the chain and there is a loud bang from the exploding cap device hidden within the rubber pull.
