Dr. Martin Luther King Jr.'s "I Have a Dream" Speech in "I'm in It"
Lyric: "Your titties, let 'em out, free at last/Thank God almighty, they free at last"
Sex talk and Dr. Martin Luther King Jr.'s "I Have a Dream" speech have been linked since Jamie Foxx in Booty Call. Chalk this up as two pop culture references in one blow. (Or three, if you count that Dr. King was quoting from a spiritual when he used it in his momentous oration.)
