Bieliebers, those youngsters who twist and shout every time they hear a Justin Bieber song, could learn a few lessons from the superfans of "Downton Abbey," which returns Sunday for Season 5.

First and foremost: Relax. You can admire an artist and a show without making such a fuss. Try having a cup of tea, or at least a diet soda. Second, learn that true greatness comes in small doses. While pop stars seem to show up on Twitter and the tabloids every nanosecond, "Abbey" is primarily open for only two months a year, making even the changing of bedsheets a precious event.

And finally, challenge yourself. Knowing every lyric to "Baby" is not going to get you into Harvard. Let those who really love the British series show you the way by mastering this ultimate quiz. Those who fall short are required to go back and re-watch previous seasons, which come to think of it, is more reward than punishment.
