That is a grounding pin. It provides a easy path for electricity to go to ground (all electricity seeks "ground" and will take the easiest path) By having the grounding pin it there it will hopefully prevent the easiest path to ground from being through YOU. Which would cause you you to get shocked.The third prong connects the body of the appliance directly to ground.

Why do you need a ground wire?
The bare (or green) grounding wire is for user safety. If there is a fault inside an appliance, a wire can become disconnected and touch other parts. If it is the "hot" side of the circuit, the parts can become energized (whether or not the switch is on). This is a dangerous hazard because a person can touch the appliance, while being grounded by touching something else, and "complete" the circuit; namely electrocution. With a safety grounding wire, there is a better chance that any parts a person could touch would be connected to the grounding wire, and thus the same hot fault would cause a short circuit to trip the breaker.

On a 3 wire plug is the wider blade hot or neutral?
On a 3 wire plug (NEMA 5 configuration, 125v 2 pole 3 wire grounding) the narrow blade is the "hot" lead, the wide blade is the neutral lead, and the U shaped prong is the equipment grounding conductor (EGC). Most 2+G non-metallic-cables (NMC) are color coded for Black = "hot", White = neutral, and Bare = EGC
