Because electricity must travel in a circuit to work. Thus, one pin is "hot", while the other is "ground". The electricity travels in on one, and out on the other.

Stuart is mostly correct. I would just like to modify his explanation a little. Yes, one pin is hot (the thinner one) and supplies the power, but the other is not ground... it is neutral (the wider pin) and does not go to ground... goes back to the powerplant. Ground would be that third pin on a 3 wire plug like on your computer which is connected to the earth (the Brits like to call it that, too).

'nuff said?
