5. Anchorman
There were about three good solid years there where you couldn't swing a cat without hearing an Anchorman reference. "I love lamp." "I DON'T KNOW WHAT WE'RE YELLING ABOUT!" "Well, that escalated quickly." And it's not that the movie isn't funny, because it is. I cherish every one of those lines and many more for the comic gold that they are. But they should be used in moderation. Every situation doesn't warrant an Anchorman quote. If you exercise a little restraint, you could probably find yourself going days without saying lines from this movie. That said, I eagerly await the sequel, even though it will inevitably bring on another few years of quoting that'll get completely out of hand.
