He'll do his pieces

I recently heard the phrase "He'll do his pieces" in an episode of Are You Being Served? and was curious about its origin. From the context I gather that it means something like to become very upset or angry, but I haven't been able to find anything on the roots of the phrase.

This is a guess. People, before mass entertainment, would "do pieces." For example, someone would recite a long poem he had memorized. Perhaps the person had a history of throwing a hissy fit, that was his "piece."
