Plastic milk carton. That might be a jug. I don't know what a jug is. I'm guessing by carton you mean one of the cardboardy type things, but I've always called the plastic ones cartons of milk. Oh you crazy Yanks.
Yes, you are right. The cardboardy ones are what I'm calling a carton. I didn't know that jugs were called cartons. They aren't even carton shaped! :Eek:
