Quick summary of Br'er Rabbit and the Tar Baby.
Br'er Fox makes a "baby" out of tar and sets it up as a trap for Br'er Rabbit. Br'er Rabbit gets stuck on the tar baby (hits it when BR thinks TB is ignoring his polite greetings, I know, it doesn't make a lot of sense). Br'er Fox comes to gloat over his captured enemy. BR begs, just begs, BF to do anything to him, except throw him into the briar patch. So of course, BF tosses BR into the briar patch. Tab baby gets caught up on the briars, BR pulls free, scampers down to the roots of the briars to run off free, BF gnashes teeth, foiled again!
