Giving away beads on Mardi Gras is a form of a unilateral contract: Men offer beads and the only way that offer can be accepted is by women flashing their baby feeders. In essence, I was obligated to give up some beads. But this begs the question of how I received my beads. Free. I received them for free. They were passed out earlier in the night. There may not be such thing as a free lunch but free "shows" do exist and I was a witness to one (or 6 since I kept surplus beads in my back pocket until the ones around my neck ran out).
