The stump speech was a comic monologue from blackface minstrelsy (which is an American entertainment consisting of comic skits, variety acts, dancing, and music, performed by white people in blackface). A typical stump speech consisted of malapropisms (the substitution of a word for a word with a similar sound), nonsense sentences, and puns delivered in a parodied version of Black Vernacular English. The stump speaker wore blackface makeup and moved about like a clown. Topics varied from pure nonsense to parodies of politics, science, and social issues, as well as satirical commentary on political and social issues. The stump speech was a precursor to modern stand-up comedy.
