What is the author's style in The Producers by Mel Brooks?

The Producers is populated with colorful characters and enlivened with witty songs filled with sly cultural references. It also relies heavily on crass and obvious stereotypes meant to offend all equally, with mincing gays, sex-object women, greedy Jews, bubble-headed Swedes, oversexed old ladies, gruff Irish cops, and kick lines of singing Nazis.
