Coon songs are way off the subject, but the backhand humor in some of these songs can't be missed.
A couple of verses from "The Traveling Coon"

That coon got on the Titanic steamship,
And sailed across the ocean blue.
When he saw that iceberg a-comin',
Right overboard he flew.

The people standin' aroun',
Said that nigger was sure a fool,
But when the Titanic ship went down,
He was shootin' craps in Liverpool.

Origin not known. Collected sometime after 1905. Probably originally from African-American minstrels for a black audience. The above verses from N. I. White. Sometimes connected to "Didn't He Ramble."
