The Back Story
Well, not so big, but following on from the Batman theme,as you all probably know the Dark Knight has the poster tagline: "Why So Serious?", which hasn't become the milkshake level of quotes but give it time, I'm sure it'll spread. Anyway watching the trailer again, I heard the words "Let's put a smile on that face" and in my head I pictures a clown that was sulking. At the time this word "sulk" didn't quite register, nor did "frown", the only think of were "An Anti-smile" or "Grimace", but I felt neither was appropriate.

Later when I came across the word Grimace twice in my reading, I thought maybe it is the same as to sulk, the characters I was reading about weren't happy. To be honest after looking it up I'm still not certain I can use the word as a replacement to frown, but I'm swaying towards not. I think it's more specific. The sort of awkward, uncontrollable "ew" factor.

Let me know if you think you know better, but only with evidence might I accept.
