It is illegal to throw life-threatening objects or foul-smelling items from a parade float.

The Law

Mardi Gras krewes have strict, legally binding regulations on what they can toss to the begging crowds. Noxious substances, live animals, and sharp objects are strictly forbidden from being used as 'throws' to prevent injury and panic. You will just have to settle for catching cheap plastic beads and aluminum doubloons.
