The very structure of American entertainment bears minstrelsy's imprint. The endless barrage of gags and puns appears in the work of the Marx Brothers and David and Jerry Zucker. The varied structure of songs, gags, "hokum" and dramatic pieces continued into vaudeville, variety shows, and to modern sketch comedy shows such as "Hee Haw" or, more distantly, "Saturday Night Live" and "In Living Color". Jokes once delivered by endmen are still told today: "Why did the chicken cross the road?" "Why does a fireman wear red suspenders?" Other jokes form part of the repertoire of modern comedians: "Who was that lady I saw you with last night? That was no lady—that was my wife!" The stump speech is an important precursor to modern stand-up comedy.
