If you pay off your bill in full every month you will not get interest charged but if you carry any balance over past the due date you will, lets say you charge 100 and pay off 99 dollars you'll start getting interest charged.
On the sarcasm part, I've heard it many times when it wasn't. I used to work customer service for a credit card company (glad I don't anymore) and I've heard way too many people blame the cards and not themselves (oh, it's the cards fault you took a two week vacation and charged $5000 and now you can't pay it back).
